Temperature can be described as an indirect measure of heat energy
So therefore your answer should be letter C
Answer:
Magnetic force, F = 0.6 N
Explanation:
It is given that,
Length of the wire, L = 30 cm = 0.3 m
Current carrying in the wire, I = 0.5 A
Uniform magnetic field, B = 4 T
To find,
The magnetic force
Solve,
A force is exerted by the wire in the magnetic field that is given by :
Here,
F = 0.6 N
Therefore, the magnetic force exerted by the wire in the magnetic field is 0.6 N
Answer:
Velocity is a vector quantity. It has both, magnitude and direction. Velocity is the rate of change in the position of a body with respect to a frame of reference. One component is the magnitude of velocity which is speed. The other one is its direction.
Explanation:
Speed is a scalar quantity.
Velocity is a vector quantity.
There are two types of quantities:
1. Scalar quantity:
A scalar quantity is a quantity which is described by its magnitude alone.
2. Vector Quantity:
A vector quantity is a quantity which is described completely by both, its magnitude and direction.
Define
u = 16 m/s, the vertical launch velocity
g = acceleration due to gravity, measured positive downward
s = vertical distance traveled
t = 21.2 s, total time of travel.
The vertical motion obeys the equation
s = ut - (1/2)gt²
When the rock is at ground level, s = 0.
Therefore
(16 m/s)(21.2 s) - 0.5*(g m/s²)*(21.2 s)² = 0
339.2 - 224.72g = 0
g = 1.5094 m/s²
Answer:
The acceleration due to gravity is 1.509 m/s² measured positive downward.
