Answer:
35.7kJ
Explanation:
we can calculate the amount of heat energy required , using this formula
Q = mcθ
where.
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat capacity (units )
θ = change in temperature (Celcius,C or Kelvin K)
Assume Specific heat capacity (c) of water =
mass =0.1 kg
D. Amplitude has no effect on velocity.
This question might have been to confuse you with the doppler effect which states that wavelengths become longer if the object causing the waves is moving away from the observer.
Answer:
Momentum
Explanation:
-Conservation means that any quantity is kept constant.❌
-Force is product of mass and acceleration.❌
-Impulse is product of force and the period of action of the force.❌
-Momentum is the product of mass of a body and it's velocity.✔️
<h2>Answer : </h2>
20cm spanner is suitable to open this nut , Because we feel easy to apply force at the end of spanner to rusted nut. It means that as the perpendicular distance between force and axis of rotation increase the magnitude of moment also increase.
I think the Answer will helps you.....
Thank you ☺️☺️☺️
Answer:
Explained
Explanation:
It is possible for the voltage amplitude across the capacitor to be greater than the voltage amplitude across the source because it is gonna charge to its peak and will add up the voltage level.Moreover,ac capacitance of capacitance can be changed by introducing di electric
so voltage can be changed !!!
