Answer: P = I2R = 0.032 x 1000 =0.9 W
Explanation: The power will be the product of the square of the current and
the resistance of the load. The fact that the circuit is a parallel circuit is irrelevant to this question.
Answer:
1964
Explanation:
It was discovered in 1964 when a pair of Geiger counters were carried on board a sub-orbital rocket launched from New Mexico.
Answer:
0.2 m/s
Explanation:
The velocity of a point on the edge of a disk rotating disk can be calculated as:

Where
is the angular velocity and r the radius of the disk. This leads to:
The answer & explanation for this question is given in the attachment below.
Answer:
Total elongation will be 0.012 m
Explanation:
We have given diameter of the cylinder = 2.1 mm
Length of wire 
So radius 
Load F = 280 N
Elastic modulus = 207 Gpa
Area of cross section 
We know that elongation in wire is given by
, here F is load, L is length, A is area and E is elastic modulus
So
