The answer is C voltmeter
Answer:
Mass will not change based on location, while weight will change based on gravitational pull.
Explanation:
The formula for weight is mass*gravitational pull, hence weight changes based on gravitational pull
Answer: in air 33.33 ps and in the glass 50 ps: so the difference 16.67 ps
Explanation: In order to calculate the time for a pulse travellin in air and in a glass we have to consider the expresion of the speed given by:
v= d/t v the speed in a medium is given by c/n where c and n are the speed of light and refractive index respectively.
so the time is:
t=d/v=d*n/c
in air
t=0.01 m*1/3*10^8 m/s= 33.33 ps
while for the glass
t=0.01 m*1.5* 3* 10^8 m/s= 50 ps
Finally the difference is (50-33.33)ps = 16.67 ps
Answer:
0.5 second
Explanation:
We are given that
Force, F=20 N
Mass, m=5 kg
Change in velocity,=2m/s
We have to find the time taken to change the velocity .
We know that
Force, F=ma
Where
Acceleration, a=Change in velocity/time
Substitute the values
