Answer:
The SI unit of power is the watt
Explanation:
Answer:
false
Explanation:
Elastic collision: the collision is said to be elastic if the kinetic energy is conserved during the collision.
If the kinetic energy is not conserved, then the collision is not elastic.
So, here no information is given so we cant say about the type of collision.
So, it is False.
Any of three muscles in each buttock that move the thigh, the largest of which is the gluteus maximus.
Answer:
Looks like you have:
a = -.324 cos 2.5 t
In this case ω^2 A = .324
ω = 2.5
f = ω / (2 * pi) = 2.5 / 6.28 = .40 / sec
Answer:
v₂ = 70 m / s
Explanation:
For this exercise let's use Bernoulli's equation
where subscript 1 is for the top of the mountain and subscript 2 is for Tuesday's level
P₁ + ½ ρ v₁² + ρ g y₁ = P₂ +1/2 ρ v₂² + ρ g y₂
indicate that the pressure in the two points is the same, y₁ = 250 m, y₂ = 0 m, the water in the upper part, because it is a reservoir, is very large for which the velocity is very small, we will approximate it to 0 (v₁ = 0), we substitute
ρ g y₁ = ½ ρ v₂²
v₂ =
let's calculate
v₂ = √( 2 9.8 250)
v₂ = 70 m / s
