Answer:
The value is
Explanation:
From the question we are told that
The first position of the fulcrum is x = 49.7 cm
The mass attached is
The position of the attachment is
The second position of the fulcrum is
Generally the sum of clockwise torque = sum of anti - clockwise torque
So
Here CWT stands for clockwise torque
So
=>
=>
Answer:
decreases.
Explanation:
When the aircraft is flies from the warm air into the colder air then its speed will be decreases.
as we know that
we know mach number is constant
so that here Mach number M is expressed as
M = .............................1
here u is Local flow velocity with respect to the boundarie and v is the speed of sound in the medium
If the aircraft flies from hot air to cold air, the speed of sound in the medium will decrease. But the Mach number remains constant. Therefore, the local flow velocity relative to the boundaries also decreases.
