Answer:
vacuum have no air. so, the hot body will remain unchanged in temperature
Explanation:
Answer:
Explanation:
The gravitational potential at a point on the Earth surface is given by:
where
G=6.67×10^-11Nm^2kg^-2 is the gravitational constant
M=5.98×10^24kg is the Earth's mass
R=6.38×10^6 m is the Earth's radius
Substituting the numbers into the equation, we find
Answer:
C. Electromagnet
Explanation:
Both a generator and a motor have an electromagnetic field caused from electricity flowing through wire wrapped in a coil.
Yes there is a benefit it is that a regular oven is faster at cooking because it can go to higher tempatures
Answer:
10 A
Explanation:
τ = Maximum torque of the loop = 9 mN
N = Number of turns in the loop = 50
a = side of the loop = 15 cm = 0.15 m
A = Area of the loop = a² = 0.15² = 0.0225 m²
B = magnitude of magnetic field = 0.800 T
i = magnitude of current in the loop
Maximum torque of the loop is given as
τ = N B i A
Inserting the values
9 = (50) (0.8) (0.0225) i
i = 10 A
