Answer:
16.3 m/s
Explanation:
We are given that
Mass of golf ball=m=0.045 kg
We have to find the speed right after the hit.


Force,F=70 N
Change in momentum=Area of trapezium
Area of trapezium,A=
Using the formula




Initial velocity of golf ball=u=0


Power = (energy) / (time)
= (60 joules) / (4 seconds)
= 15 joules/second
= 15 watts
Answer:
Explanation:
Let the required velocity of rocket be v .
We shall use the formula of time dilation to find the velocity of rocket .
t =
t = 430
t' = 38


= .0078
=.9922
= .996
v = .996 x 3 x 10⁸ m /s
= 2.988 x 10⁸ m /s
B )
Kinetic energy of rocket
= 1/2 m v²
= .5 x 20000 x (2.988 x 10⁸ )²
= 8.9 x 10²⁰ J .
C )
This energy is 8.9 times the energy requirement of United states in the year 2005 .
Answer:
Output voltage is 1.507 mV
Solution:
As per the question:
Nominal resistance, R = 
Fixed resistance, R = 
Gauge Factor, G.F = 2.01
Supply Voltage, 
Strain, 
Now,
To calculate the output voltage,
:
WE know that strain is given by:

Thus

Now, substituting the suitable values in the above eqn:


That's false.
There are billions of galaxies in the universe. A few of the nearest ones are moving TOWARD us, and ALL the rest are moving AWAY from us.
The farther a galaxy is from us now, the faster it's moving farther away.
