Answer:
It continue to move forward at a constant velocity which will be slower than before the front thruster was fired.
Explanation:
Before the front thruster was fired, the spacecraft was already moving at a particular velocity.
After the malfunction, the front thruster is fired and then the force exerted by that front thruster slows the spacecraft down, as we are told.
By using the rear thruster to exert a force equal to that from the front thrusters, a force equal in magnitude to that of the front thrusters is added, cancelling out the effect of the front thrusters. Because the spacecraft is already moving at a slower speed at this point compared to the beginning, it continues to move at that speed.
Answer:
F = 150 N
Explanation:
Torque being applied by parent
= F x r
where F is force applied tangentially and r is point of application of force from axis of rotation ( center )
given torque = 240 Nm
r = 1.6 m
F x r = 240
F x 1.6 = 240
F = 150 N
So a force of 150 N is applied by the parent to achieve the given torque.
This force will also be applied by the merry - go- around on the parent as reaction force according to Newton's third law. The parent will not be pushed back by this force because he is standing on a rough surface . Friction of surface will help him remain stationary on the ground.
Frequency is indirectly proportional to the wavelength, in other words, when frequency increases wavelength decreases and vice-versa
c = ∧f
Hope this helps!
The correct option is A.
A telescope is an optical instrument that is used to observe celestial bodies in order to gather information about them. There are different types of telescopes but all of them have some common parts. One of the common parts is the eye piece. The eye piece is the part of the telescope that one looks through and is the part that makes the focused light visible to the eye. The eye piece is made up of magnifying lenses.<span />
Explanation:
It is given that,
Force on piston, F₁ = 8800 N
Area, 
Area, 
Let F₂ is the force exerted on the second piston. Using Pascal's law as :
Pressure at piston 1 = Pressure at piston 2
So, the force exerted by a second piston is 35200 N. Hence, this is the required solution.
