Answer:
<u>Yes, it will be a Home Run</u>
Explanation:
(Note : It is assumed that the collision between bat and ball is perfectly elastic.)
( Also I don't know anything about baseball, so I checked the dimensions online, which are minimum 325 ft (left and right field foul pole) and minimum 400 ft centre field fence)).
<u>STEP 1</u>
<em>Find</em><em> </em><em>Horizontal</em><em> </em><em>Range</em><em> </em><em>of</em><em> </em><em>Projectile</em><em> </em>
Therefore, the ball will travel 560.3 ft horizontally well beyond 400 ft (largest dimension of the field), and it'll be a Home Run.
Answer:
v = 1.224 m/s
Explanation:
given,
distance between the two successive maxima = 1.70 m
number of crest = 8
time = 11 s
frequency is equal to number of cycle per secod
velocity of wave
v = f x λ
v = 0.72 x 1.70
v = 1.224 m/s
Hence, the wave speed is equal to v = 1.224 m/s
Here's a formula that's simple and useful, and if you're really in
high school physics, I'd be surprised if you haven't see it before.
This one is so simple and useful that I'd suggest memorizing it,
so it's always in your toolbox.
This formula tells how far an object travels in how much time,
when it's accelerating:
Distance = (1/2 acceleration) x (Time²).
D = 1/2 A T²
For your student who dropped an object out of the window,
Distance = 19.6 m
Acceleration = gravity = 9.8 m/s²
D = 1/2 G T²
19.6 = 4.9 T²
Divide each side by 4.9 : 4 = T²
Square root each side: 2 = T
When an object is dropped in Earth gravity,
it takes 2 seconds to fall the first 19.6 meters.
When visible light, X rays, gamma rays, or other forms of electromagnetic radiation are shined on certain kinds of matter, electrons are ejected. That phenomenon is known as the photoelectric effect. The photoelectric effect was discovered by German physicist Heinrich Hertz (1857–1894) in 1887. You can imagine the effect as follows: Suppose that a metal plate is attached by two wires to a galvanometer. (A galvanometer is an instrument for measuring the flow of electric current.) If light of the correct color is shined on the metal plate, the galvanometer may register a current. That reading indicates that electrons have been ejected from the metal plate. Those electrons then flow through the external wires and the galvanometer. HOPE THIS HELPED
