People who have been struck by lightning do not carry an electrical charge and can be touched is True.
heat lightning is lightning flashes in the sky that do not have the accompanying sound of thunder so false just like the others
You can use Vf^2-Vi^2 = 2ax
Vf^2 - 0 = 2(9.81)(25)
Or you can use energy
mgh = 1/2mv^2
2gh =v^2
Same thing
Answer:
B. decreases while his angular speed remains unchanged.
Explanation:
His angular speed will always be the same as the wheel's angular speed, which remains constant as it's in uniform motion. As for linear speed, which is defined as the product of angular speed and distance r to the center of rotation, and his distance to center is decreasing, his linear speed must be decreasing as well.
Answer:
v= 1495.04 m/s
Explanation:
The formula for velocity of sound is given by ;
v= fλ --------where
v= velocity of sound
f= frequency of turning fork
λ = wavelength
However,
Δ L = 1/2 λ ------where Δ L is spacing between resonances.
1.46 = 1/2 λ
1.46 * 2 = λ
2.92 m = λ
v= fλ
v= 512 * 2.92
v= 1495.04 m/s
