Answer:

F_{resultant} = 1 [m/s]

Explanation:

These types of problems can be solved by means of relative velocities, where vectors (forces or velocities) are necessarily handled, these velocities depending on the velocity are added or subtracted.

Forces to the right are taken as positive and negative to the left.

[tex]F_{velocity}-F_{air}=F_{resultant}\\2-1 = F_{resultant}\\\\F_{resultant} = 1 [m/s][/tex]

Answer:

338.7cm

Explanation:

The can of corn would be in the shape of a cylinder. Since we are looking at capacity, we will want to find the volume.

V=abase×h

V=πr2×h

V=π(d2)2×h

V=π(6.62)2×9.9

V=338.7cm3

Hopefully this helps!

Answer:

338.7 cm³

Explanation:

For this question you use the volume formula of a cylinder πr²h.

Radius is 1/2 the diameter.

Simply input the variables into the formula.

π(3.3)²×9.9 = 107.811π or approximately 338.7 cm³

Answer:

According to Newton's second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known

Answer:

5600 + 6650 = 12250

Explanation:

Answer:

t=v/a

Explanation:

Acceleration is defined as the rate of change of velocity with time. It is mathematically expressed as;

  Acceleration  = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]  

The change in velocity per unit of time is the acceleration

 From this equation;

      time  = [tex]\frac{change in velocity }{acceleration}[/tex]  

This expression is analogous to the expression chosen.

Answer:

621.83grams

Explanation:

Using the formula;

Mole = mass ÷ molar mass

Where;

Mole = mol

Mass = grams

Molar mass = g/mol

According to the information given in this question, number of moles = 3.1mol, mass of Hg = ?, Molar mass (MM) of Hg = 200.59g/lol

Hence, using mole = mass/MM

3.1 = mass / 200.59

mass = 200.59 × 3.1

Mass = 621.829

Mass = 621.83grams

Answer:

D. Time t = 1 [s]

Explanation:

To solve this problem we must use the following equation of kinematics.

[tex]v_{f}=v_{o}-g*t[/tex]

where:

Vf = final velocity = 0 (when the ball reaches the maximum height its elevation won't be increased since the velocity is zero)

vi = initial velocity = 10 [m/s]

g = gravity acceleration = 10 [m/s²]

t = time [s]

Now replacing:

[tex]0 = 10-10*t\\10 = 10*t\\t = 1 [s][/tex]

Answer:

  0.6 seconds

Explanation:

The time to fall from height h is ...

  t = √(2h/g)

  t = √(2(1.86 m)/(9.8 m/s^2)) ≈ √0.3796 s ≈ 0.616 s

It would take about 0.6 seconds for the projectile to hit the ground.

Answer:

Radiation

Explanation:

bc Radiation transfers heat through electromagnetic waves.

Answer:

2.52moles

Explanation:

The amount of substance, measured in miles, can be calculated using the formula:

Number of moles = mass ÷ molar mass

According to the information in this question; mass of Mercury (Hg) = 505g, molar mass (MM) of Hg = 200.59g/mol

Hence, using mole = mass/MM

mole = 505/200.59

mole = 2.5175

mole = 2.52moles

Answer:

[tex]\boxed {\boxed {\sf 299.568 \ Joules }}[/tex]

Explanation:

Kinetic energy can be found using the following formula:

[tex]E_k=\frac{1}{2}mv^2[/tex]

where m is the mass and v is the velocity.

The mass of the person is 60 kilograms and the velocity is 3.16 meters per second

[tex]m= 60 \ kg \\v= 3.16 \ m/s[/tex]

Substitute the values into the formula.

[tex]E_k=\frac{1}{2} (60 \ kg) *(3.16 \ m/s)^2[/tex]

First, evaluate the exponent.

[tex]E_k=\frac{1}{2}(60 \ kg ) (9.9856 \ m^2/s^2)[/tex]

Multiply 60 kg by 9.9856 m²/s²

[tex]E_k=\frac{1}{2} (599.136 \ kg*m^2/s^2)[/tex]

Multiply 599.136 kg*m²/s² by 1/2, or divide by 2.

[tex]E_k=299.568 \ kg*m^2/s^2[/tex]

[tex]E_k= 299.568 \ J[/tex]

The running person has a kinetic energy of 299.568 Joules.

Solution:

We know that, Kinetic energy(kE)= 1/2×m×v^2

By applying formula,we get

Or,KE=1/2×60×3.16^2

Or,kE=299.57j

So,her kinetic energy is 2999.5j

Cosmic Dust.

Why? When stars explode, or die, they releases dust and gas.

To solve this we must be knowing each and every concept related to galaxy. Therefore, cosmic dust of a galaxy consists of tiny particles that look smoky or cloudy and can be found in the space between stars.

Galaxies are collections of stars as well as other celestial objects that are gravitationally bound. The cosmos contains and over 100 billion galaxies, each of which has stunning formations seen in photographs captured by telescopes of the far sky.

According to Samuel, a galaxy's shape is the result of continual interactions between its many components. The majority of the mass is provided by the dark matter, which uses gravity to hold everything together. Cosmic dust of a galaxy consists of tiny particles that look smoky or cloudy and can be found in the space between stars.

Answer:

The gravitational force between two objects = F = 9.3 x 10⁻⁶ N        

Explanation:

Given

m₁ = 70 kg

m₂ = 2000 kg

distance r = 1 m

Thus, the gravitational force between two objects = F = Gm₁m₂ / r²

as

Gravitation constant = G = 6.67430×10⁻¹¹ N⋅m²/kg²  

Thus, putting the values

F = Gm₁m₂ / r²

  = (6.67430×10⁻¹¹ × 70 × 2000) / 1²

   = 9.3 x 10⁻⁶ N

Thus, the gravitational force between two objects = F = 9.3 x 10⁻⁶ N                                            

Answer:

The correct option is C

Explanation:

The pendulum bob would return at the same time because the initial angle a pendulum bob is dropped does not affect it's period (the time it takes for the pendulum to move back and forth), however the one with a larger angle move faster but would eventually arrive at the same "starting point" due to varying displacements made.

c. No one wins as the bobs come back at the same time.

Answer:

You should weigh about 16 pounds.

Explanation:

To find this, you need to find your weight and divide it by 6 to find your weight on the moon.

Answer:

The weight of an object with mass M, in a place with gravitational acceleration G, is:

W = M*G

We know that in the moon, with G = 1.6 m/s^2, the weight is 160N

Then we have the equation:

160N = (1.6 m/s^2)*M

With this, we can find the mass of the astronaut.

(160N)/(1.6 m/s^2) = M = 100kg.

Then in the Earth, where the acceleration is G = 10 m/s^2, the weight will be:

W = (10m/s^2)*100kg = 1000 N

Answer:

The value of the horizontal velocity when the pumpkin is thrown is approximately 17.619 m/s

Explanation:

The height from which the pumpkin is thrown = 14 meters

The velocity with which the pumpkin is thrown = 23 m/s

The direction in which the pumpkin is thrown = 40° above the horizontal

The horizontal component of the velocity = 23 × cos(40) ≈ 17.619

Therefore, the value of the horizontal velocity when the pumpkin is thrown ≈ 17.619 m/s
