Answer:
f = 0.5 Hz
Explanation:
frequency = f
wave length = l
speed of wave = v
f = v/l → f = 3/6 = ½ = 0.5 Hz
most fossils are found in sedimentary rocks
Answer:
velocity
Explanation:
the displacement of an object during a specific unit of time.
Answer:
The statement that the net magnetic field at the center of this square is zero is false.
The net magnetic field inside a conductor must be zero - This is a true statement
Explanation:
The net magnetic field at the center of this square is not equal to zero.
The net magnetic field at the center of this square is given by the equation below:
B = 2√2μ₀I/πₐ
Where a = the side of the loop, and I is the current.
Thus, the statement that the net magnetic field at the center of this square is zero is false.
The net magnetic field inside a conductor must be zero - This is a true statement because the total charge on the conductor must be equal to zero.
Answer:
Explanation:
Given
Total run=198 m
maximum speed=317 m/min=5.28 m/s
acceleration
(a)Distance traveled while accelerating
s=12.57 m
time taken
v=u+at
t=4.75 s
(b)Time taken to cover 198 m
if car takes 12.57 m & 4.75 s to reach max speed so it also takes 12.57 m and 4.75 s to stop from max speed
Distance traveled with max speed=198-25.14=172.86 m
time taken
total time=4.75+32.73+4.75=42.25 s
