Answer:
The question is incomplete. I will assume you intend to find the total momentum of the two carts during collision. Therefore, we can use the conservation of momentum principle to get the total momentum at a certain instant before collision.
Explanation:
The conservation of momentum principle states that the initial net momentum of two bodies before collision is equal to the final net momentum after collision.
In this case, let's denote the rolling cart as <em>'a'</em> and the stationary cart as <em>'b'</em>.
Therefore, the total momentum before collision is 11.02 Kg.m/s.
Explanation:
The net force along the horizontal direction is
where f is the frictional force. We can find the frictional force by looking at the vertical forces acting on the couch:
From the definition of frictional force,
Therefore, the net force on the couch is
High specific heat of the water. Option (c)
What is Specific heat?
The amount of heat required to increase the temperature of one gram of a substance by one degree Celsius is referred to as the substance's specific heat. Typically, calories or joules are used per gram and degree Celsius when referring to the units of specific heat.
The moderate temperature of islands has much to do with the water's high specific heat. The typical off-water is more significant than this clear land or soil. Due to this fact, water absorbs and releases eat more slowly. In comparison to the land.
Hence, the water has high specific heat.

Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
