It's b, because the more force an object it is given the harder it will be for it to slow down.
Earthquakes and volcanoes most commonly occur around plate boundaries because of the movement from the plate boundaries. The interactions between the plates by moving under, upon, or sliding against other boundaries may cause earthquakes and volcanoes.
Explanation:
Below is an attachment containing the solution.
Answer:
The magnitude of the magnetic field halfway between the wires is 3.0 x 10⁻⁵ T.
Explanation:
Given;
distance half way between the parallel wires, r = ¹/₂ (40 cm) = 20 cm = 0.2 m
current carried in opposite direction, I₁ and I₂ = 10 A and 20 A respectively
The magnitude of the magnetic field halfway between the wires can be calculated as;

where;
B is magnitude of the magnetic field halfway between the wires
I₁ is current in the first wire
I₂ is current the second wire
μ₀ is permeability of free space
r is distance half way between the wires

Therefore, the magnitude of the magnetic field halfway between the wires is 3.0 x 10⁻⁵ T.
Answer:
1.57 s
Explanation:
Since the motion of the hammer is a uniformly accelerated motion, the distance covered by the hammer in a time t is

Where, in this case
S = 2.0 m is the distance covered
a = 1.62 m/s^2 is the acceleration due to gravity
t is the time taken
Re-arranging the equation, we can find the time the hammer takes:
