Answer:
<em>The crane lifts the crate up to 76 m high</em>
Explanation:
<u>Work Done by a Force</u>
The work done by a force of magnitude F that displaces an object by a distance y is given by
We know a crane does a work of 9,500 Joule to lift a crate and is using a force of 125 Nw.
The above equation can be solved to know the value of y in terms of the work and the force:
Plugging in the given values
The crane lifts the crate up to 76 m high
Answer:
Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm
Explanation:
Given ;
Average speed = 3.5cm/year
Time= 1 s
Distance = speed × time
Number of seconds in a year = 31536000 sec/year
Distance = 3.5 cm/year × 1/31536000sec/year × 1 s
Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm
Answer:
The magnetic field at the center of a circular loop is .
Explanation:
Given that,
Radius = 4.0 cm
Current = 2.0 A
We need to calculate the magnetic field at the center of a circular loop
Using formula of magnetic field
Where, I = current
r = radius
Put the value into the formula
Hence, The magnetic field at the center of a circular loop is .
