Hey there,
Your correct answer would be proximity. Proximity is <span>principle illustrates our tendency to group items together based on how close they are to each other.

m = mass of pellet = 2.10 x 10⁻² kg
x = compression of spring at the time launch = 9.10 x 10⁻² m
h = height gained by the pellet above the initial position = 6.10 m
k = spring constant
using conservation of energy
spring potential energy = gravitational potential energy of pellet
(0.5) k x² = m g h
inserting the values
(0.5) k (9.10 x 10⁻²)² = (2.10 x 10⁻²) (9.8) (6.10)
k = 303.2 N/m
The answer is (B. The study of Matter and Energy) but technically you could consider physics all of these as engineering is based on physics and that would be the study of inventions, chemistry and biology were both discovered because of physics, and physics invokes more math than any other subject as it applies math to the entire Universe.
Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that the magnetic force on the current carrying wire is given as
so we have
so we have
Part b)
Now magnetic field is changed to 0.55 T
so we will have
