Answer: Object B
The velocity of object A is depicted in the graph as a straight line (constant speed therefore no acceleration).
The graph indicates that the velocity of object B increases (the object is accelerating).
Answer:
<h3>4.0Wb/m²</h3>
Explanation:
Magnetic flux Ф is expressed using the formula;
Ф = BA
B is magnetic field
A is the area of the square conductor
Given
B = 1.0T
A =L²
Area A = 2.0² = 4.0m²
Get the magnetic flux
Ф = 1.0 * 4.0m²
Ф = 4.0Wb/m²
Hence the magnetic flux through the conductor is 4.0Wb/m²
Answer:
d. All three statements are true.
Explanation:
In the metals the electrons are the charge carriers and they are the only mobile charges causing the flow of current when subjected to potential difference.
The electrons being negatively lead to the flow of current in opposite direction. The direction of the current is opposite to the direction of the negative charges.
Answer:
D. The cart is moving at a constant speed or velocity
Explanation:
Equilibrium is a state of body in which it is either at rest or moves with uniform velocity. The sum of forces acting on such a body is always zero and the sum of all the torques acting on it is also zero.
There are two types of equilibrium as follows:
Static Equilibrium: When a body is at rest it is said to be in static equilibrium.
Dynamic Equilibrium: When a body is moving with constant velocity, then it is said to be in dynamic equilibrium.
Hence, the correct option here will be:
<u>D. The cart is moving at a constant speed or velocity</u>
