Answer:
6.1 m/s
Explanation:
Take up to be positive. Given (in the y direction):
Δy = 1.4 m
vᵧ = 0 m/s
g = -10 m/s²
Find: v₀ᵧ
vᵧ² = v₀ᵧ² + 2aΔy
(0 m/s)² = v₀ᵧ² + 2 (-10 m/s²) (1.4 m)
v₀ᵧ = 5.29 m/s
The vertical component is 5.29 m/s. So the total magnitude of the initial velocity is:
v₀ᵧ = v₀ sin θ
5.29 m/s = v₀ sin 60°
v₀ = 6.11 m/s
Rounding to two significant figures, the fish must spit the water at 6.1 m/s.
That is an example of a Law. Specifically, that is called as
Law of Magnetism. It is one of the physical laws or scientific laws we have. A
physical law is a theoretical statement is the conclusions of repeated scientific
observations and experiments over the year.
Answer:
Yes.
Explanation:
-This is because the threshold voltage for the green light is much lower than that of the blue light.
-A longer wavelength in the greenlight necesitates the need for a lower voltage in the banana plug.
They tend to be lustrous, ductile, malleable, and good conductors of electricity, while nonmetals are generally brittle (for solid nonmetals), lack lustre, and are insulators.
