The force acting on the passenger is equal to:
Where N is the normal force and mg is a force of gravity. If a person feels like their weight is increased by 60% at the bottom that means normal force is 60% stronger than the force of gravity:
We know that net force must be equal to the centripetal force:
Answer:
Explanation:
Let the cross sectional area be a cm .
volume of hydrometer inside liquid = 12 x a = 12 a
weight of liquid displaced = 12a x .8 x g = 9.6 a g
For free floatation of liquid
weight of hydrometer = weight of displaced liquid
9.6 a g = 100 g
a = 10.41 cm²
cross sectional area = 10.41 cm².
Answer:
The same in both the regions of constructive interference and the regions of destructive interference.
Explanation:
Interference is a phenomenon which occurs when two waves meet while moving along the same medium . The amplitude formed as a result of the interference could be greater, lower, or the same amplitude.
Constructive and destructive interference result from the interaction of waves that are correlated or coherent with each other. This is because arose from the same source or they have the same or nearly the same frequency.
The waves being coherent, arising from the same source and having the same frequency explains why it’s the same in both the regions of constructive interference and the regions of destructive interference.
Given:
Force, F = 30 N
Acceleration, a = 2 m/s^2
Let's determine the mass of the object.
To find the mass(m) of the object, apply the formula below:
Rewrite the formula for mass(m):
Where:
F = 30 N
a = 2 m/s^2
Thus, we have:
Therefore, the mass of the object is 15 kg
ANSWER:
15 kg
1. that's 2 joules 1*2 = 2 j
2.that will be 20*3.5 = 70 j
3.that will be = 500*2.2= 1100 j
