Answer:

force (tension) of 29.4 N (upward)  in 100 cm

force (tension) of 58.4 N (upward)  in 200 cm

Explanation:

Given:

Length of tube = 5 m (500 cm)

Mass of tube = 9

Suspended vertically from 150 cm and 50 cm.

Computation:

Force = Mass × gravity acceleration.

Force = 9.8 x 9

Force = 88.2 N

So,

Upward forces = Downward forces

D1 = 150 - 50 = 100 cm

D2 = 150 + 50 = 200 cm

And F1 = F2

F1 x D1 = F2 x D2

F1 x 100 = F2 x 200

F = 2F

Total force = Upward forces + Downward forces

3F = 88.2

F = 29.4 and 2F = 58.8 N

force (tension) of 29.4 N (upward)  in 100 cm

force (tension) of 58.4 N (upward)  in 200 cm

Answer:

a) The baseball spends 0.674 seconds in the air

b) The horizontal distance from the roof edge to the point where the baseball lands on the ground = 2.02 m

Explanation:

The ball's initial speed, u = 3.8 m/s

θ = 38°

The edge of the roof has a height, H = 3.30 m

The vertical motion of the baseball can be given by the equation:

[tex]H = U_{y} t + 0.5a_{y} t^{2}[/tex].........(1)

Vertical acceleration of the baseball, [tex]a_y = 9.8 m/s^2[/tex]

The vertical component of the initial speed can be calculated by:

[tex]U_y = Usin \theta\\U_y = 3.8 sin 38\\U_y = 2.34 m/s[/tex]

Substituting the appropriate values into equation (1):

[tex]3.8 = 2.34 t + 0.5(9.8)} t^{2}\\4.9t^2 + 2.34t - 3.8 = 0[/tex]

Solving for t in the quadratic equation above:

t = 0.674 s

To calculate the horizontal distance, S, use the formula below:

[tex]S = U_xt + 0.5a_xt^2[/tex]

Horizontal acceleration of the baseball, [tex]a_x = 0 m/s^2[/tex]

The horizontal component of the initial speed can be calculated as:

[tex]U_x = Ucos \theta\\U_x = 3.8 cos 38\\ U_x = 2.99 m/s[/tex]

S = 2.99(0.674) + 0.5(0)

S = 2.02 m

The other guy made me get the question wrong lol here ya go good luck

Answer:

Yes, the fuse will blow.

Explanation:

We'll begin by converting 50000mA to amperes (A) .this is illustrated below:

1000mA = 1A

Therefore, 50000mA = 50000/1000 = 50A.

From the question given above, the plug can only accommodate 5A. Now if 50000mA i.e 50A is passed through the plug, the plug will blow because the 50A is higher than what the plug can accommodate.

Answer: c.mesosphere

Explanation: Temperatures can reach lows of -90 degrees Celsius in the mesosphere, making it the coldest layer of the earth's atmosphere. The mesosphere extends above the stratosphere and ranges from 50 km to 87 km above the surface.

Answer:

i. + 22.5 m ii. 4.0 m

Explanation:

i. Image distance

Using the lens formula

1/u + 1/v = 1/f where f = focal length = + 18.0 m, u = object distance = distance of shark away from lens = + 90.0 m and v = image distance from lens = unknown

So, we find v

1/v = 1/f - 1/u

= 1/+18 - 1/+90

= (5 - 1)/90

= 4/90

v = 90/4

= + 22.5 m

So the image is real and formed 22.5 m away on the other side of the lens.

ii Length of Shark

Using the magnification formula, m = image height/object height = image distance/object distance. image height = 1.0 m where object height = length of shark.

m = image distance/object distance

= v/u

= +22.5/+90

= 0.25

0.25 = image height/object height

So,

object height = image height/0.25

= 1.0 m/0.25

= 4.0 m

So, the length of the shark is 4.0 m

This is due to gas expanding within balloon.The expanding gas causes the balloons to reach maximum height and it burst.

Answer:

A and C

Explanation:

The easiest way to solve this is by drawing a new triangle, one where one leg is clearly longer than the other.  This way, it is easy to see which angles match.

Or, using geometry, we can show that C = θ since they are alternate interior angles.  Since C is complementary to the angle between the rays, and A is also complementary to the angle between the rays, then A = C, so A = θ.

Explanation:

Mitosis is important for growth and development  of living organisms.

The major importance of mitosis is growth and development. The correct option is B.

Mitosis is the method by which a cell replicates as well as then segregates its chromosomes, and generates two identical nuclei in order to divide.

Mitosis is basically followed by the equal division of the cell's contents into two daughter cells with identical genomes.

Mitosis occurs in the following stages:

One cell divides once during mitosis to form two identical cells. Mitosis is primarily responsible for cell growth and replacement.

Thus, the correct option is B.

Answer:

83.33s

Explanation:

velocity=300km/hr ,acceleration =1m/s2

But before we can make this calculation,we have to make sure that both the acceleration and velocity are in the same units.So I decided to Chang the velocity to m/s.

Converting 300km/hr into m/s;

Changing 300km into m=300000m

Changing 1hr into secs=3600sec

Velocity in m/s=83.33m/s

But Time =velocity/acceleration

=83.33/1

=83.33sec

You have to decide what you want.  Your question says "Find the average velocity", but the choices you listed are all times, not velocities.

(300 km/hr) x (1 hr / 3600 sec) = 83.33 meters/sec

-- If the airplane starts from rest and accelerates uniformly at 1 m/s², it'll take 83.33 seconds to reach takeoff speed.

-- If it starts from rest and accelerates uniformly to 83.33 m/s, then its average speed is 41.67 m/s no matter what its acceleration may be.

Answer:

False , The fatty layer do not contains many nerves and blood vessels. The fatty layer is related to skin layers.

Explanation:

The fatty layer is the most under a layer of skin. It made up of a system of collagen and fat cells. It helps maintain the body's temperature and shields the body from harm by serving as a shock absorber.

The dermis is the central layer of the skin. The dermis is maintained collectively by a protein termed collagen. This layer gives skin elasticity and power. The dermis also holds shock and feel receptors.

Answer:

No. of Cars = 8

Explanation:

In order to find the no. of buses that can be cleared by the daredevil, we first need to find the distance he will cover during its motion. Since, the motion is projectile, therefore, the horizontal distance will be equal to range of the projectile:

R = V² Sin 2θ/g

where,

R = Range = ?

V = launch speed = 43 m/s

θ = angle with horizontal = 30°

g = 9.8 m/s²

Therefore,

R = (43 m/s)² Sin 60°/(9.8 m/s²)

R = 163.4 m

Now, for the number of cars cleared, we use the following formula:

No. of Cars = R/Length of single bus

No. of Cars = 163.4 m/20 m

No. of Cars = 8.17

No. of Cars = 8

Explanation:

When a person is standing still, the forces acting on them (weight force pulling down and normal force pushing up) are equal and opposite, so the net force is balanced.  So the person will continue to be at rest, unless the net force becomes unbalanced.

When a person falls with a parachute, the forces acting on them (weight force pulling down and air resistance pushing up) are equal and opposite, so the net force is balanced.  So the person will continue to fall at the same speed until the net force becomes unbalanced.

Answer: 0.625N

Explanation:

Given the following:

Magnetic field Force = 0.25N

Length of wire = 8cm

Current = 3.0 ampere

The force that the same field will exert on another wire 20cm long carrying the same current will be :

Since current 'I' is the same ;

0.25 Force = 8cm

x force = 20cm

Cross multiply:

8x = (20 × 0.25)

x = (20 × 0.25) / 8

x = 5 / 8

x = 0.625

Force = 0.625N

Answer:

A magnetic field exerts a force of 0.25 N on an 8.0 cm length of wire carrying a current of 3.0 A at right angles to the field. Calculate the force that the same field would exert on another wire 20 cm long carrying the same current. I WILL GIVE BRAINLY

Answer: it is called a open circuit

Explanation:

Answer:

This is because white light consists of 7 colours with different angles o deviation or retraction.

Explanation:

When a narrow beam of light is refracted by a prism the light spreads into a band of colours (called the spectrum of light )

But in this case if a blue colour is observed it is due to the angle of refraction ,for instance red is refracted the least and hence is seen

Answer:

When while light is diffracted and at a particular location blue color is seen, this means that blue color is reflected while all other colors will be absorbed. When the blue color is seen denotes the shortest wavelength being reflected and all other being absorbed at the specified location.

The fission reactions include

239 Pu + n → Ce + Kr + 2n

And

295 Am + in → 154 La + 95 Sr + 3 n

Explanation:

A fission reaction is a radioactive reaction in which an atom with a heavy nuclei splits into atoms with smaller or lighter nuclei usually brought about by the attack of a fundamental particle and accompanied by the release of some fundamental particles (neutrons mostly) and energy.

Although, the reactions to be examined aren't totally clear, we can still guess which element is which and know which of the reactions has a heavier nuclei splitting into smaller ones.

1) H + H → He + 2n

Two hydrogen atoms combine to give an helium atom and release neutrons too, showing that here, smaller molecules combine to form a bigger one. Hence, this isn't a fission reaction, rather, it's a fusion reaction.

2) 239 Pu + n → Ce + Kr + 2n

Here, Pu (Plutonium, atomic mass 239), a heavy nuclei that splits into smaller nuclei, Ce (Cerium, atomic mass 140) and Kr (Krypton, atomic mass 84) together with some neutrons to fit the definition of a fission reaction. Hence, this reaction is a fission reaction.

3) 295 Am + n → 154 La + 95 Sr + 3 n

Here, Pu (Americium, atomic mass 295), a heavy nuclei that splits into smaller nuclei, Ce (Lamthanium, atomic mass 154) and Sr (Strontium, atomic mass 95) together with some neutrons to fit the definition of a fission reaction. Hence, this reaction is a fission reaction.

4) 13C + H → 14N

Carbon 13 combines with a hydrogen element to mutate and give nitrogen-14, a heavier nuclei, showing all signs of a nuclear fission and not fission.

Answer:

Approximately [tex]2.31\; \rm m \cdot s^{-2}[/tex] (assuming that the acceleration due to gravity is[tex]g = 9.81\; \rm m \cdot s^{-2}[/tex].)

Explanation:

Assuming that [tex]g = 9.81\; \rm m \cdot s^{-2}[/tex] the weight on this 72-kg skydiver would be [tex]W = m \cdot g = 72 \; \rm kg \times 9.81\; \rm m \cdot s^{-2} = 706.32\; \rm N[/tex] (points downwards.)

Air resistance is supposed to act in the opposite direction of the motion. Since this skydiver is moving downwards, the air resistance on the skydiver would point upwards.

Therefore, the net force on this skydiver should be the difference between the weight and the air resistance on the skydiver:

[tex]\begin{aligned}F(\text{net force}) &= W - F(\text{air resistance})\\ &= 706.32\; \rm N - 540\; \rm N =166.32\; \rm N \end{aligned}[/tex].

Apply Newton's Second Law of motion to find the acceleration of this skydiver:

[tex]\begin{aligned}a &= \frac{F(\text{net force})}{m} \\ &= \frac{166.32\; \rm N}{72\; \rm kg} = 2.31\; \rm m \cdot s^{-2} \end{aligned}[/tex].

Answer:

a.) L = 2.64 kgm^2/s

b.) V = 4.4 m/s

Explanation: Jessica stretches her arms out 0.60 m from the center of her body. This will be considered as radius.

So,

Radius r = 0.6 m

Mass M = 2 kg

Velocity V = 1.1 m/s

Angular momentum L can be expressed as;

L = MVr

Substitute all the parameters into the formula

L = 2 × 1.1 × 0.6 = 1.32kgm^2s^-1

the combined angular momentum of the masses will be 2 × 1.32 = 2.64 kgm^2s-1

b. If she pulls her arms into 0.15 m,

New radius = 0.15 m

Using the same formula again

L = 2( MVr)

2.64 = 2( 2 × V × 0.15 )

1.32 = 0.3 V

V = 1.32/0.3

V = 4.4 m/s

Her new linear speed will be 4.4 m/s
