true or false Newtons's First Law states "Acceleration depends on the mass of the object and the unbalanced force applied"

babunello [35]

False, his first law states: An object that's in motion will remain in motion at a constant velocity unless it's acted on by an unbalanced force.

The gravitational attraction between a 20 kg cannonball and a 0.002 kg

Naya [18.7K]

Answer:

$2.966\times 10^{-11}\ N$

Explanation:

Given:

Mass of the cannonball (M) = 20 kg

Mass of the marble (m) = 0.002 kg

Distance between the cannonball and marble (d) = 0.30 m

Universal gravitational constant (G) = $6.674\times 10^{-11}\ m^3 kg^{-1} s^{-2}$

Now, we know that, the gravitational force (F) acting between two bodies of masses (m) and (M) separated by a distance (d) is given as:

$F=\dfrac{GMm}{d^2}$

Plug in the given values and solve for 'F'. This gives,

$F=\frac{(6.674\times 10^{-11}\ m^3 kg^{-1} s^{-2})\times (20\ kg)\times (0.002\ kg)}{(0.30\ m)^2}\\\\F=\frac{6.674\times 20\times 0.002\times 10^{-11}\ m^3 kg^{-1+2} s^{-2}}{0.09\ m^2}\\\\F=2.966\times 10^{-11}\ kg\cdot m\cdot s^{-2}\\\\F=2.966\times 10^{-11}\ N.........(1\ N = 1\ kg\cdot m\cdot s^{-2})$

The same force is experienced by both cannonball and marble.

Therefore, the gravitational force of the marble is $2.966\times 10^{-11}\ N$

A planet's rotation determines the length of its day and its revolution determines the length of its year. A day on Earth is 24

Sholpan [36]

Explanation:

The speed of rotation of Venus is slower than that of Earth that is why a day on Venus is longerthan Earth's day. Whereas, Venus is closer to sun than Earth, this means Venus trajectory of revolution is smaller than that of Earth.Therefore, a year on Venus is shorter than Earth's year.
