the bell, the balloon

expanded
Answers
When the pump removed the air in the bell, the balloon expanded.
Option: B
Explanation:
In order to construct our own environment in the glass jar known as bell jar system, which can be used to explore and consider our larger environment on Earths, for an instance. Here a glass jar that hinges on an airtight rubber basis i.e seals appropriately. At the top of the jar, a bung is connected to it which passed via a metal tube. It has an adjacent flexible tube that goes to a hand vacuum pump and the best hand-powered pump was made with a wine preserver.
When the pump extracts the air from the bell jar, the pressure inside the balloon naturally decreases. The balloon usually has a air pressure around it, which restricts its size, but when this air is extracted and the pressure around it decreases the gas in the balloon will expand and the balloon seems to be inflating. When you release the air back into the bell jar, it will once again compress back to its actual size.

Answer
the anser is (C) as 240 Watt
Explanation
As we know that
As given in question
Force = 150 N
Distance = 4m
Then work is
So the answer is 240 watt

The wavelength and frequencyincrease (decrease) in proportion to energy levels. Short wavelengths have a higher energy than long wavelengths because of the link between wavelength and frequency, which dictates that the higher the frequency, the shorter the wavelength.
What is energy?
Energy is defined as the capacity of a physical system to perform work.
Wavelength is related to energy and frequency by
E = hν = hc/λ,
where E = energy, h = Planck's constant, ν = frequency, c = the speed of light, and λ = wavelength
The number of waves that pass a specific place in a predetermined period of time is known as the wave frequency. The hertz is the wave frequency SI unit (Hz)
The distance between two successive crests or troughs of a wave is known as its wavelength. It is calculated using the wave's direction.
The wavelength and frequencyincrease (decrease) in proportion to energy levels.

Acceleration = (force) / (mass)
If there is no friction . . .
Acceleration = (200N) / (50 kg) = 4m/s²
Change in speed = (acceleration) x (time) = (4 m/s²) x (10 sec) = 40 m/s
Final speed = (speed of the cart before the force began) + (40 m/s more)
(That's about 89 mph faster than the cart was moving before the force started.)
Initial velocity (vi): 0 m/s
Final velocity (vf): ?
Acceleration (a): ?
Force (F): 200 N
Mass (m): 50 kg
Time (t): 10 s
F= ma
200 N= (50kg)(a)
a= +4 m/s^2
a= (vf-vi)/t
+4 m/s^2= (vf - 0m/s)/10s
vf= 40 m/s
Answer: the cart will be moving 40 m/s.

Answer:
The current in the coil is 60 Ampere.
Explanation:
Given:
Number of turns in the coil is N = 25
Dimension of the coil = 15cm X 12cm
magnitude of magnetic field = 0.20T
angle in the xy plane is θ = 0 degree
torque τ = 5.4 N-m
To find:
current in the coil is i = ?
Solution:
The torque acting on the coil is given by
=>
Converting cm to m
12 cm = 0.12 m
15 cm = 0.15 m
The area of the coil is
A = 0.12 X 0.15
A =
Substituting the values
=>
=>
=>
=>
=>
=>
=> i = 60 A
