Answer:
The answer to your question is Q = 10.5 J
Explanation:
Data
C = 4.180 J/kgK
mass = 50 g
Temperature 1 = 298°K
Temperature 2 = 348°K
Formula
Q = mCΔT
Process
1.- Calculate ΔT
ΔT = Temperature 2 - Temperature 1
ΔT = 348 - 298
ΔT = 50°K
2.- Convert g to kg
1000 g -------------- 1 kg
50 g ------------- x
x = (50 x 1)/ 1000
x = 0.05 kg
3.- Substitution
Q = (0.05)(4.180)(50)
4.- Simplification
Q = 10.45 J
5.- Result
Q = 10.5 J
Explanation:
We have,
Electric field intensity is 700 N/Cj
It is required to find the magnitude and direction of the acceleration of this electron due to this field.
The electric force is balanced by the force due to its motion i.e.
qE =ma
a is acceleration of this electron
So, the acceleration of the electron is and it is moving in +y direction.
Answer:
Explanation:
Net force by which man push the lawn mower is given as
now it is given that 37% of this force is vertically downwards
so we will have
now we also know that
here we have
Now work done by this force to move the lawn mower is given as
Geothermal energy. People around the world use it for electricity. Such as heating and other purposes.
