From the Hooke's law , the extension force of an elastic material is directly proportional to the extension.
That is, F = k e, where F is the force , k is the constant and e is the extension
F = 10 × 10 = 100 N
e = 1mm or 0.001 m
Hence, k = F/e
= 100 N/ 0.001
= 100000 N/m or 100 N/mm

Answer:
<h2>30 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 15 × 2
We have the final answer as
<h3>30 kg.m/s</h3>
Hope this helps you
Answer:
A derived unit is called so because it is the product of two more basic units. The basic unit of area is the cubic meter (m³) for volume. By derived unit, it refers to any given quantity which cannot be measured directly with any device. For eg., We can't measure density of a substance with a rule, or scale, or bucket.
Answer:
The induced emf in the coil is
Explanation:
From the question we are told that
The magnitude of the emf for a single loop is
The number of turn of the new wire is N = 5
The magnitude of the emf induced in the coil is
substituting value
