A moon of mass 1×1020 kg is in a circular orbit around a planet. The planet exerts a gravitational force of 2×1021 n on the moon. The centripetal acceleration of the moon is most nearly.

If the mass of the moon is equal to 1 x 10²⁰ kg and the gravitational force exerted by the planet is equal to 2 x 10²¹ N, then the centripetal acceleration of the moon is equal to 20 m/s².What is centripetal acceleration?Centripetal acceleration is defined as the constant change in velocity for an object to maintain a circular path. Recall that change in velocity is called acceleration. One way for an object to accelerate is to change direction. An object that is constantly changing directions is accelerating.We're given that the mass of the moon is equal to 1 x 10²⁰ kg and the gravitational force of the planet is equal to 2 x 10²¹ N. To find the centripetal acceleration, we'll only need to divide the force by the mass since acceleration is equal to force over mass (a = F/m).The centripetal acceleration of the moon is calculated as follows:a = F/ma = (2 x 10²¹) / (1 x 10²⁰)a = 2 x 10¹a = 20a = 20 means the centripetal acceleration is equal to 20 m/s².Learn more about acceleration here: https://brainly.com/question/460763#SPJ4
