Explanation :  

The angular velocity of the planet in the elliptical orbit will vary. Its shows that the planet  travel slower when farther from the sun, then faster when closer to the sun.

1. Yes, Earth experiences the strongest gravitational force when it is closest to the Sun.

2. Yes,  Earth moves the greatest distance in thirty days when it is closest to the Sun.

3. Yes,  Earth travels with the slowest tangential speed when it is farthest from the Sun.

4. Yes,  Earth sweeps out the same area in the same time frame anywhere in its orbit

Kepler's second law : Kepler describe the motion of the planets around the sun. the line joining the planet and the sun sweeps out  the same area in the same time.

A sample of nitrogen gas has a volume of 5.0 ml at a pressure of 1.50 atm. what is the pressure exerted by the gas if the volume
olchik [2.2K]

A sample of nitrogen gas has a volume of 5.0 ml at a pressure of 1.50 atm. what is the pressure exerted by the gas if the volume increases to 30.0 ml, at constant temperature is 0.25atm.

On constant temperature, the pressure and volume relation become constant before and after the change in quantitities have occurred.

According to Boyle's Law,

P₁V₁ = P₂V₂

where, P₁ is pressure exerted by the gas initially

V₁ is the volume of gas initially

P₂ is pressure exerted by the gas finally

V₂ is the volume of gas finally

Given,

P₁ = 1.5 atm

V₁ = 5 ml

V₂ = 30 ml

P₂ =?

On substituting the given values in the above equation:

P₁V₁ = P₂V₂

1.5 atm × 5 ml = P₂ × 30 ml

P₂ = 0.25 atm

Hence, pressure exerted by the gas is 0.25atm.

A 23.7 kg kid slides down a
anyanavicka [17]

Answer:

\text { The acceleration of the kid is } 7.18 \mathrm{m} / \mathrm{s}^{2}

Explanation:

Mass of the kid 23.7 kg.

\text { The kid is accelerating down at an angle is } 47.2^{\circ} .

^{\prime \prime} \mathrm{g}^{\prime \prime} \text { acceleration due to gravity is } 9.8 \mathrm{m} / \mathrm{s}^{2}

We need to find the acceleration of the kid,

We know that, Parallel force acted on the kid at an angle is

F = m × g × sinθ (F = ma)

m × a = m × g × sinθ

Now, substitute the given values in the above formula to find acceleration of the kid,

23.7 \times a=23.7 \times 9.8 \times \sin 47.2^{\circ}

23.7 × a = 232.26 × 0.733

23.7 × a = 170.24

a=\frac{170.24}{23.7}

a=7.18 \mathrm{m} / \mathrm{s}^{2}

\text { Therefore, acceleration of the kid is } 7.18 \mathrm{m} / \mathrm{s}^{2}

Blank is a measure of how fast something moves
quester [9]

Answer: average speed  

  The overall rate of speed at which an object moves: calculated by dividing the total distance an object travels by the total time

instantaneous speed >      The speed of an object at one instant in time.

velocity                    >                Speed in a given direction
