D because 15 kg weighs less and therefore it will result in the greatest change in speed
Let me know if I’m right
Answer:
0.00158 A
Explanation:
A = Area of loop = 7.8 cm²
= Final magnetic field = 3.2 T
= Initial magnetic field = 0.5 T
R = Resitance = 
The emf is given by
The current is given by
The resulting induced current in the loop is 0.00158 A
Answer:
Any material that keeps energy such as electricity, heat, or cold from easily transferring through is an insulator
A conductor is a material which contains movable electric charges.
Baking a cake creates a endothermic reaction. When heated, the baking soda/powder reacts, the eggs change form, and everything else follows suit. The baking soda/powder creates the rising of the cake.
Answer:
Options A, B, and C are all possible.
Explanation:
We know that the instantaneous velocity of the dog at 3:14PM is possitive to toward the flowers. But what about the acceleration to toward the flowers?
If the dog is decreasing speed at 3:14PM, it means that acceleration is negative toward the flowers, hence (since F=ma) the net force points away from the flowers.
If the dog is increasing speed at 3:14PM, it means that acceleration is positive toward the flowers, hence (since F=ma) the net force points toward the flowers.
If the dog is not increasing nor decreasing speed at 3:14PM, it means that acceleration is 0, hence (since F=ma) the net force is null and it does not point neighter to toward the flowers nor away from the flowers. This happens when the forces acting on the dog are equal to both sides.
