<u>Answer:</u>
The ball is rolling at a speed of 0.02 meter per second.
<u>Step by step explanation:</u>
We are given that there is a 800 gram bowling ball rolling in a straight line. If its momentum is given to be 16 kg.m/sec, we are to find its velocity.
For this, we will use the formula of momentum.
<em>Momentum = mass × velocity</em>
16 = 800 × velocity
Velocity = 16/800 = 0.02 meter per second
Answer:
The current pass the
is 
Explanation:
The diagram for this question is shown on the first uploaded image
From the question we are told that
The voltage is 
The first resistance is 
The second resistance is 
Since the resistors are connected in series their equivalent resistance is

Substituting values


Since the resistance are connected in serie the current passing through the circuit is the same current passing through
which is mathematically evaluated as

Substituting values


<span>(symbol K)</span><span> Energy that an object possesses because it is in motion. It is the energy given to an object to set it in motion; it depends on the mass (</span>m) of the object and its velocity (v<span>), according to the equation K = 1/2 </span>mv2<span>. On impact, it is converted into other forms of energy such as heat, sound and light.</span>
Answer:
14 m/s²
Explanation:
Start with Newton's 2nd law: Fnet=ma, with F being force, m being mass, and a being acceleration. The applied forces on the left and right side of the block are equivalent, so they cancel out and are negligible. That way, you only have to worry about the y direction. Don't forget the force that gravity has the object. It appears to me that the object is falling, so there would be an additional force from going down from weight of the object. Weight is gravity (can be rounded to 10) x mass. Substitute 4N+weight in for Fnet and 1kg in for m.
(4N + 10 x 1kg)=(1kg)a
14/1=14, so the acceleration is 14 m/s²
