Geothermal energy is earths natural heat
Answer:
Explanation:
Given that,
The speed of the car is
Vc = 97m/s
The radius of circular path of the car is
Rc = 420m
We want to find the angle of roadway banked β?
To determine the angle of roadway banked, we will use the formula
tanβ = Vc² / Rc•g
Where Vc = 97m/s, Rc = 420m and
g = 9.8m/s²
Then
tanβ = 97² / (420 × 9.8)
tanβ = 2.28596
β = ArcTan ( 2.28596)
β = 66.37°
The railway banked at an angle of 66.37°
Answer:
The acceleration is
Explanation:
From the question we are told that
The radius is
The magnitude of the magnetic field is
The rate at which it decreases is
The distance from the center of field is
According to Faraday's law
and
Where the magnetic flux
E is the electric field
dl is a unit length
So
Now is the circumference of the circular loop formed by the magnetic field and it mathematically represented as
A is the area of the circular loop formed by the magnetic field and it mathematically represented as
So
Substituting values
The negative signify the negative which is counterclockwise
The force acting on the proton is mathematically represented as
Also
So
Where m is the mass of the the proton which has a value of
So
Answer:
Adding heat makes the particles move faster so the particles have more kinetic energy when more thermal energy is added
Explanation:
Answer:
making the size of the car bigger is good
