Weight refers to the force of gravity acting on a mass. We often calculate the weight of an object by multiplying its mass by th
1 answer:
Answer:
85 Kg
314.041 N
Explanation:
We are given that
Mass of body on earth=85 kg
Acceleration due to gravity on earth=
Weight of body on earth=830 N
We have to find the mas of body and weight of body on Mars.
We know that mass of an object does not change with location .
It remain same everywhere.
Mass of body on Mars=85 kg
Gravitational acceleration on the surface of Mars=
We know that
Weight =
Using this formula
Weight of body=
Hence, the weight of body on Mars=314.041 N

Answer:
Stay the same
Explanation:
First of all, let's find how the capacitance of the capacitor changes.
Initially, it is given by
where
is the vacuum permittivity
A is the area of the plates
d is the separation between the plates
From the formula, we see that the capacitance is inversely proportional to the separation between the plates. In this problem, the distance between the plates is doubled, so the capacitance will be halved:
The potential difference across the capacitor is given by
where
Q is the charge on the plates
C is the capacitance
We see that the voltage is inversely proportional to the capacitance. We said that the capacitance has halved: therefore, the potential difference across the two plates will double:
Now we can analyze the electric field between the plates of the capacitor, which is given by
we said that:
- The voltage has doubled: V' = 2 V
- The distance between the plates has doubled: d' = 2 d
therefore, the new electric field will be
So, the electric field is unchanged. And since the force on the particle at the center is directly proportional to the electric field:
F = qE
Then the force on the particle will stay the same.
For these question, it has two separate equations: 2f(a) and f(2a) .
For f(2a) equations its x=2a, so you must substitute 2a into the f(x) equation
For 2f(a), it means the two time of f(a) equation with x=a, so you substitute a inti f(x) equation first, then you multiply it by 2.
