Answer: Hand span
Explanation: Hand span is not a standard unit.
Second is the unit of time.
Meter is the unit of length or distance covered by an object.
Gram is the unit of weight of an object.
Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".
There will be 4 forces on the phone in total.
1. gravity
2. normal force from the windshield
3. dynamic friction
4. a push from the car
The sum of all 4 forces must achieve an acceleration of 23,6 cm/s² or a total force of F = m * a = 0.1774kg * 0.236m/s² = 0.0419N.

Answer:
Explanation:
Given that
For sphere
Is = 110msD²
For cube
Ic = 16mcS²
D= S
We know that time period of torsion pendulum is directly proportional to the square root of the rotational inertia.
Now by putting the values
Answer:i
Induced emf will be equal to 83.25 volt
Explanation:
We have given value of inductance L = 1.85 H
Initially the current flow is equal to 0.450 A
When switch is open current become 0 in 10 ms
So change in current di = 0.450-0=0.450 A
Time taken to change the current dt = 10 ms = 0.01 sec
Induced emf is equal to
So
Induced emf will be equal to 83.25 volt
