The answer is 37 cause the two sides squared and added together equals the hypotenuse squared after that you just find the square root of the answer
Answer:
74.4 kilowatts or 99.8 horsepower
Explanation:
The explanation is in the attachment.
Answer:
Explanation:
wave length of light λ = 502 nm
screen distance D = 1.2 m
width of one fringe = 10.2 mm / 20
= .51 mm
fringe width = λ D / a , a is separation of slits
Puting the values given
.51 x 10⁻³ = 502 x 10⁻⁹ x 1.2 / a
a = 502 x 10⁻⁹ x 1.2 / .51 x 10⁻³
= 1181.17 x 10⁻⁶ m
1.18 x 10⁻³ m
= 1.18 mm .
The time elapsed when the ball reaches the window is 1.55s
As per the question:
Final velocity, v = 11 m/s
Height, h = 29m
Acceleration, a = g = -9.8 m/s
From the third equation of motion:
v² = u² +2as
u² = v² - 2as
u² = (11)² - 2 × (-9.8) × (29)
u² = 689.4
u = √689.4
u = 26.25 m/s
Now, from the first equation of motion:
v = u + at
t = 1.55 s
Therefore, the time elapsed when the ball reaches the window is 1.55s.

The linear velocity of the wheel is 16 m/s.
<h3 /><h3>What is linear velocity?</h3>
Linear velocity is the rate of change of displacement with regard to time when the object is moving in a straight line
To calculate the linear velocity of the wheel, we use the formula below.
Formula:
- v = ωr............. Equation 1
Where:
- v = Linear velocity
- ω = Angular velocity
- r = Radius of the wheel.
From the question,
Given:
Substitute these values into equation 1
Hence, The linear velocity of the wheel is 16 m/s.
