Answer:
the sides of the wedge are inclined.
Explanation:
The wedge is a triangular simple machine with a blunt face and two inclined faces. The distribution of forces in a wedge is because the sides of the wedge are inclined.
V= 1/3 π r²h
this is the formula for a cone hope this helps :)
Answer:
The answer is A ) High pressure
I hope this helps you :)
please let me know if I am wrong
Answer:
Work done by external force is given as

Explanation:
As per work energy Theorem we can say that work done by all force on the car is equal to change in kinetic energy of the car
so we will have

now we have


so from above equation

so from above equation work done by external force is given as

Answer:
1 μC extra charge will be flow here
Explanation:
Given data
battery V1 = 4.0 V
flows Q1 = 6.0 μC
replace battery V2 = 7.0 V
to find out
what happen if we replace battery
solution
we apply here principal of capacitor
that is Q directly proportional voltage
so we say Q2/Q1 = V2/ V1
put all value here
Q2/Q1 = V2/ V1
Q2/6 = 7/ 6
Q2 = 7
so we see here 7 μC will be flow
and Q = Q2 - Q1 = 7 - 6 = 1 μC
so we also say that 1 μC extra charge will be flow here
