F=9/5C+32 is the formula for Celsius to Fahrenheit.
A vector would be a quantity that has both magnitude and direction.
Answer:
0.48 m
Explanation:
I'm assuming that this takes place in an ideal situation, where we neglect a host of factors such as friction, weight of the spring and others
If the mass is hanging from equilibrium at 0.42 m above the floor, from the question, and it is then pulled 0.06 m below that particular position. This pulling is a means of adding more energy into the spring, when it is released, the weight compresses the spring and equals its distance (i.e, 0.06 m) above the height.
0.42 m + 0.06 m = 0.48 m
At the highest point thus, the height is 0.48 m above the ground.
Answer:
0.76 s
Explanation:
We are given that
Length of rod,L=20 cm=
1 m=100 cm
Mass of rod,M=190 g=
Mass of ball,m=19 g=
Using 1 kg=1000g
We have to find the period if the rod and clay swing as a pendulum.
Moment of inertia of rod-clay=Moment of inertia of rod+moment of inertia of clay


Substitute the values then we get


Now, the center of mass of the combination of the rod and clay is given by

Substitute
=Distance between pivot and the center of the rod
The distance between rod and clay
Using the formula

m
Time period of the oscillation of the system of the rod and the clay is given by

g=
Using the formula
Time period=
Time-period=0.76 s
Hence, the period =0.76 s
