a) We use the formula:
T = [g sinθ – a] * m
where g is gravity, θ is the angle, a is acceleration, m is mass
T = [9.81 sin37 - 2.00] * 12 = 46.85 N <span>
b) We use the formula for moment of interia:</span>
I = T * r² / a
I = 46.85 * 0.10² / 2.00 = .2343 kg∙m² <span>
c) The formula we can use here is:</span>
w = α * t = (a/r) * t
w = (2/.10) * 2
<span>w = 40 rad/sec</span>
Answer:
Its velocity also changes
Explanation:
Answer:
d
Explanation:
This is because momentum is defined as p = mv
delta p = Force *time
neither velocity nor time is given so a conclusion cannot be made on which has the greatest momentum change.
Answer:twice of initial value
Explanation:
Given
spring compresses 
distance for some initial speed
Suppose v is the initial speed and k be the spring constant
Applying conservation of energy
kinetic energy converted into spring Elastic potential energy
When speed doubles
divide 1 and 2
Therefore spring compresses twice the initial value
Answer:
The magnetic force on a current-carrying wire is perpendicular to both the wire and the magnetic field with direction given by the right hand rule.
