Answer:
100 Watts
Explanation:
<u>These equations are needed to work out the answer:</u>
- power= work done/ time taken
- work done= force* distance
- force= mass* acceleration
force: 10 kg* 2m/s= 20
work done: 20* 10m=200
power: 200/2=100
The answer is 1/4
this is actually a very simple question because if you divide 3,600 by 4 that equals 900 so if you want them to be the same waight you need 3,600 to be multiplied by 1/4.
Vertical component = 2.25 N downward
Horizontal component = 1.05 N to the right
Magnitude of the net force = √ (2.25² + 1.05²)
= √6.165 = 2.483 N (rounded)
Direction of the net force = tan⁻¹ (1.05/2.25) to the right of downward
= tan⁻¹ ( 7/15 ) to the right of downward
= 25° to the right of downward (rounded)
Ike is at the beach watching the waves in the ocean. Ike notices that some of the waves are short. Other waves are very tall and come up high above the water. Two waves that are different heights because They have different amplitudes.
Answer: Option (D) is correct
Explanation:
The different heights of the waves are due to their different amplitudes. The Amplitude of a particular wave depends upon the amount of energy being carried by waves. It the waves carry more energy than their amplitude will be higher.
But if energy carried by a wave is less than the wave will have a low amplitude. The Amplitude shows the distance covered from the rest position to peak position.
Answer:
P = 2161 N
Explanation:
For this exercise, let's start with Newton's second law
P - W = m a
P = ma + W
Where P is the fin force, W the weight,
Let's look for the vertical acceleration of the fish, this goes from a vertical speed of zero to a speed of 6.20 m / s when it has traveled half its length 1.50
y = 0.75 m
v² = v₀ + 2 a y
a = v² / 2 y
a = 6.20²/2 0.75
a = 25.63 m / s
We substitute in Newton's second law
P = m (g + a)
Let's calculate
P = 61.0 (0 9.8 + 25.63)
P = 2161 N
