Answer:
Mass of the body will be = 6 kg
Explanation:
Given:
Mass of an object = 6 kg
Acceleration due to gravity of the planet = 10 
To find the mass of the body on that planet.
Solution:
Mass of the body is defined as the total amount of matter contained in the body.
Thus, mass of a body will always remain constant irrespective of the acceleration due to gravity. This is because it is an independent quantity and does not vary with acceleration due to gravity.
<em>It is the weight of the body that changes with the change in the acceleration due to gravity as it is given by:</em>
where 
represents mass of the body and 
represents the accelration due to gravity.
Hence, the mass of the given body will remain = 6 kg.
Answer:
28km/h
Explanation:
92km = 4 hours
176 - 92 = 84
84km = 3 hours
84/3 = 28
28km/h
Hopefully this helps you :)
pls mark brainlest ;)
Answer:
Electric field, E = 
Explanation:
Given that,
The potential difference across the membrane, 
The thickness of the membrane is, 
We need to find the magnitude of the electric field in the membrane. We know that the relation between electric field and electric potential is given by :
So, the magnitude of the electric field in the membrane is .
Answer:
Explanation:
Speed of car =22.5miles/hr
U=22.5miles/hour
Applied brake and come to rest
Final velocity, =0
t, =2sec
Given that,
Speed=distance /time
Then,
Distance, =speed, ×time
Converting mile/hour to m/s
Given that
Use: 1 mile= 1600 m, 1 h= 3600s
22.5miles/hour × 1600m/mile × 1hour/3600s
Therefore, 22.5mile/hour=10m/s
Using speed =10m/s
Distance =speed ×time
Distance=10×2
Distance, =20m
The distance travelled before coming to rest is 20m.
Answer:
One might think of a plucked guitar string - the sound would depend on the original amplitude of the disturbance -
Speed and velocity would still be the same
(b) is correct because the energy transfer depends on the original energy applied.
