Answer:
potential energy is the ability to do work
I think the answer would be C. because the orbit around the sun compared to the Earth's (Identifies the seasons change and the year) would be longer, but the day is unknown because that is where it would come down to the total mass of the planet and other important factors about the planets properties.
Answer:
Given that
Now it is given that
Now the distance can be calculates as
Differentiating with respect to 't' and equating to zero for minimizing the function we get
The shortest distance is thus given by
Answer: Option C) 9.63 joules
Explanation:
Mass of object = 8.8kg
Speed of object = ?
Kinetic energy = ?
Momentum of the object = 13 kgm/s
Recall that momentum is a product of mass M and speed V of a moving object.
Thus, Momentum = Mass x Speed
13 kgm/s = 8.8kg x V
V = (13kgm/s ➗ 8.8kg)
V = 1.48 m/s
Now, that the speed of the object is known, calculate its kinetic energy. And, its kinetic energy depends on its mass M and speed, V
Thus, Kinetic energy = 1/2 x mv^2
= 1/2 x 8.8kg x (1.48m/s)^2
= 0.5 x 8.8kg x (1.48m/s)^2
= 4.4 x (1.48m/s)^2
= 9.63 joules
Thus, the kinetic energy of the object is
9.63 joules
