Answer:
The value is
Explanation:
From the question we are told that
The acceleration is
Generally the force by which the truck bed (truck) is moving with is mathematically represented as
Now for the truck cabinet to slip from the truck bed then the frictional force between the truck cabinet is equal the force by which the the truck bed is moving with that is
Here is the frictional force which is mathematically represented as
substituting into above equation
=>
substituting values
Answer:
The magnitude of the force on the wire is 2.68 N.
Explanation:
Given that,
Length of the wire, L = 5 m
Magnetic field, B = 0.37 T
Angle between wire and the magnetic field,
Current in the wire, I = 2.9 A
We need to find the magnitude of the force on the wire. The magnetic force in the wire is given by :
So, the magnitude of the force on the wire is 2.68 N. Hence, this is the required solution.
Answer:
840 W
Explanation:
The energy expended in hoisting the diver up is given by
<em>m</em> is the mass of the diver, <em>g </em>is the acceleration due to gravity and <em>h</em> is the height.
Using the values in the question and taking <em>g</em> as 9.8 m/s²,
The power is given by
<em>t</em> is the time.
Hence,
