Answer:
A)196J
B)-208J
C)3467J
Step-by-step explanation:
We are given that a 20 kg cylindrical mass is dropped onto the mat from a height of 1 m above the mat. During the impact, the cylinder’s vertical velocity reaches zero at the instant the mat has compressed to only 4 cm thick.
So, The Mat gets compressed by : 10cm - 4 cm = 6 cm=0.06 m
a)
Using Conservations of energy
Potential energy at the top = Kinetic energy at the point before touching the surface
Kinetic energy = mgh=
b)
Work done by the mat do to stop the fall of the cylinder =
C)
Work done=
F=3467J
Answer:
A rectangle or a right angle
Step-by-step explanation:
Answer:
0.000071
Step-by-step explanation:
The given number that is given in scientific notation is, ............(1)
We need to write this number in standard notation. A number can be written in scientific notation as :
..........(2)
In standard notation,
So, is equivalent to . Hence, the correct option is (d)
Well since 27% in decimal form is .27, that mean .48 is greater.
27% < 0.48
The values of and are and , respectively.
In this question we need to solve the linear equation for each point, first for and later for .
If we know that , then the value of is:
If we know that and , then the value of is:
