Carole is very tired and makes coffee. Why would Newton say that she must use her hand to pick up the cup? A) The idiom that eve

ry action has an equal and opposite reaction applies. B) An object at rest will stay in at rest unless acted upon by an external force. C) Acceleration of the object is indirectly proportional to the balanced forces. D) The coffee's inertia accelerates with the force due to the unbalanced forces

Answer:

The correct answer is  option B.

Explanation:

Newton laws of motion:

1.An object will remain at rest or in motion in a straight line unless an external force tries to change its state.

2. The force is equal to the change in momentum with respect to time.

        Force = mass × Acceleration

3. Every action has an equal and opposite reaction.

So, when in order to pick her cup she has to exert some force on cup which was at rest. Moment she exerts the force on cup to pick she just changes its state from rest to motion.

Construct a graph of position versus time for the motion of a dog, using the data in the table below. Explain how the graph indi
Lynna [10]

Answer:

The dog is moving at a constant speed

Explanation:

Given that,

Position : 5, 10, 15, 20, 25

Time = 5. 10, 15, 20, 25

We need to draw a position time graph

Using given data

A graph of position and time shows the speed.

According to graph,

The graph indicates that the dog is moving at a constant speed because the graph is straight line.

Hence, The dog is moving at a constant speed

a catcher "gives" with the ball when he catches a 0.196 kg baseball moving at 31 m/s. if he moves his glove a distance of 5.32 c
Aloiza [94]

Answer:

3540.5N

Explanation:

Step one:

given data

mass m= 0.196kg

speed  v= 31m/s

distance r= 5.32cm = 0.0532m

Step two

The expression relating force, mass, velocity and distance is

F= mv^2/r

substitute we have

F=0.196*31^2/0.0532

F=0.196*961/0.0532

F=188.356/0.0532

F=3540.5N
