Answer:
12824.74 N
Explanation:
mass of bullet, m = 21 g = 0.021 kg
distance, s = 114 cm = 1.14 m
final velocity, v = 1180 m/s
initial velocity, u = 0
Let F be the force .
By use of work energy theorem
Work done = change in kinetic energy
F x s = 1/2 m v² - 1/2 mu²
F x 1.14 = 0.5 x 0.021 x 1180 x 1180
F = 12824.74 N
Answer:
energy
Explanation:
waves can move distances without transferring any matter, so the answer is energy

Answer:
the change in energy of the block due to friction is
Explanation:
From the question we are told that
The frictional force is
The mass of the block is
The length of the ramp is
The height of the block is
The change in energy of the block due to friction is mathematically represented as
The negative sign is to show that the frictional force is acting against the direction of the block movement
Now substituting values
Answer:
The Coulomb’s Law is as follows
According to this law, the force between two charged objects can be calculated using the distance between the objects. If the objects are large, then it is not possible to determine the distance, r, between that object and the other object. Because, the edge of the object contain charges as well as the center of the object.
In that case, you need to separate the object into infinitesimal points, apply the formula to those points, then integrate over the large object to find the force between objects.
