Answer:
a)
b)
Explanation:
From the question we are told that:
Dimensions:
Current
Magnetic field
Therefore
a)
Generally Force on Looping gives
Therefore
b)
Generally the equation for Torque is mathematically given by
Since A and B are on opposite direction
Therefore
F = ma
m = F/a
m = 20N / 5m/s^2
m = 4kg
Answer:
254
Explanation:
use the formula "final Velocity- initial velocity / time = acceleration"
so "X - 14 /4 = 60"
60 x 4 = X - 14
240 +14 = X
X = 254
Answer:
Biodiversity decline continues due to a rapidly expanding human population. Habitat is damaged in order to meet growing needs for agriculture, urban development, water and materials. Fish, wildlife and plants are overharvested, despite mounting evidence that many harvesting practices are unsustainable.
