Answer:

F1 = 16 N and F2 = 24 N

Explanation:

Formula used => F = m×a and v-u= at

So, as we know force = mass × acc.

so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now

Here u= 0 as the objects are placed at rest initially..

thus, v= at

FOR 1ST BLOCK

16= <math> F1/5 </math> × 5 ==> F1 = 16 N

FOR 2ND BLOCK

15= <math> F2/ 8 </math> × 5 ==> F2= 24 N

Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.

Graph for the two magnets held apart, kinetic energy is highest when the magnets first released, then it decreases steadily. Energy stored in the magnetic field becomes zero.

The magnetic field is the field in the space and around the magnet in which the magnetic field can be filled.

Magnetic force is the force of attraction or repulsion between two poles of the two magnets. The magnetic force is also appearing between two electrically charged bodies.

Two magnets held apart. Once released, the south pole of one magnet moves toward the north pole of another magnet until the magnets collide.

The graph reflection of kinetic energy of magnet -

Therefore, graph for the two magnets held apart, kinetic energy is highest when the magnets first released, then it decreases steadily. Energy stored in the magnetic field becomes zero.

Answer:

Option d (108,000 J) is the correct answer.

Explanation:

The given values are:

Power,

P = 120 Watts

Time,

t = 15 min.

i.e.,

 = 900 sec

As we know,

⇒ [tex]P=\frac{W}{t}[/tex]

So,

⇒ [tex]W=P\times t[/tex]

On substituting the given values, we get

Answer:

Turning on a light bulb.

Answer:

See explanation

Explanation:

Range of a projectile is given by; U^2sin2θ/g

When θ = 45°

The maximum range is obtained as;

Rmax = U^2/g

Maximum range on earth = RME = U^2/g

Maximum range in the moon= RMM =U^2/g/6

Maximum range in Mars = RMMA = U^2/0.38g

a)

RME/RMM =  U^2/g/U^2/g/6

RME/RMM = 6

But RME = 3 m

RMM = 3 * 6 = 18 m

b)

RME/RMMA =U^2/g/U^2/0.38g

RME/RMMA = 1/0.38

But RME = 3 m

RMMA = 3/0.38

RMMA = 7.9 m

Answer:

2450 J

Explanation:

Given that,

A 50Kg girl jumps off a 5-meter-high diving board.

We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,

[tex]K=mgh\\\\K=50\times 9.8\times 5\\\\K=2450\ J[/tex]

So, her kinetic energy right before she hits the water is equal to 2450 J.

Answer:

The radius of the curve is 9,183.67 m.

Explanation:

Given;

velocity of the jet plane, v = 600 m/s

acceleration of the jet plane, a = 4g = 4 x 9.8 m/s² = 39.2 m/s²

The radius of the curve is calculated from centripetal acceleration formula as given below;

[tex]a = \frac{v^2}{r} \\\\r = \frac{v^2}{a} \\\\r = \frac{600^2}{39.2} \\\\r = 9,183.67 \ m[/tex]

Therefore, the radius of the curve is 9,183.67 m.

Answer:

the smallest radius of the circular path is 8.1 km

Explanation:

The computation of the smallest radius of the circular path is given below:

Given that

V = Velocity = 201 m/s

a_c = acceleration = 5 m/s^2

radius = ?

As we know that

a_c = V^2 ÷ r

5 = 201^2 ÷ r

r = 201^2 ÷ 5

= 8,080.2 g

= 8.1 km

Hence, the smallest radius of the circular path is 8.1 km

Answer:

See answer below

Explanation:

In order to do this, we just need to apply the expression to determine the time of flight. This is given by:

t = 2 V₀ Sinθ / g   (1)

We have the initial speed which is 200 m/s, the angle of elevation to the horizontalis 60° and the gravity is 9.8 m/s². Replacing this data in the above expression we have:

t = 2 * 200 Sin60° / 9.8

Now that we have the time, we can determine the range or distance in the horizontal plane. This can be calculated using the following expression:

X = V * t   (2)

We already have the time, which is the time of flight, the initial speed using cos 60° (Cause it's horizontal plane), and replacing we have:

X = 200 cos60° * 35.348

X = 100 * 35.348

Answer:

hope my answer helps

Explanation:

second law of reflection states that the angle of incidence equals to the angle of reflection,

this is the basic relationship,

so the angle of incidence is also equals to angle of reflection

According to www.open.edu,

Elements are substances that are made from one type of atom.

Compounds are substances made from atoms of different elements joined by chemical bonds.

A mixture is made by simply mixing together elements and compounds.

Atoms are the basic building blocks.

i think A is incorrect because, while the statement may be correct, it is talking about Mixtures, not elements themselves!

B is incorrect because elements ARE able to combine to form compounds!

D is incorrect because ELEMENTS combine to create compounds, i am pretty sure compounds don't combine to create elements.
