The restoring force of the spring cancels the weight of the mass, so by Newton's second law
∑ F = F[spring] - mg = 0 ⇒ F[spring] ≈ 45.1 N
where m = 4.60 kg and g = 9.80 m/s². Then the spring constant is k such that by Hooke's law,
F[spring] = k x
where x = 0.0231 m. Then the spring constant is
k = F[spring]/x ≈ 1950 N/m
The number and units. An example would be 3cm or 4kg.
Answer:
The emf is 0.574 volt.
Explanation:
Given that,
Magnetic field
Length = 75.0 m
Velocity = 255 m/s
We need to calculate the emf
Using formula of emf
Where, v = velocity
l = length
B = magnetic field
Put the value into the formula
Hence, The emf is 0.574 volt.
Given: Mass m = 44 Kg; Velocity v = 10 m/s
Required: Kinetic energy K.E = ?
Formula: K.E = 1/2 mv²
K.E 1/2 (44 Kg)(10 m/s)²
K.E = 2,200 Kg.m²/s²
K.E = 2,200 J Answer is A
