Answer: Option B: 1.3×10⁵ W
Explanation:
Work Done,
Where s is displacement in the direction of force and F is force.
where, v is the velocity.
It is given that, F = 5.75 × 10³N
v = 22 m/s
P = 5.75 × 10³N×22 m/s = 126.5 × 10³ W ≈1.3×10⁵W
Thus, the correct option is B
From what I have been told, the four basic forces regarding physics are the strong or powerful force, a gravitational force, an electromagnetic force, and a weak force. The strong force binds nuclei. Weak forces take care of nuclear decay. Electromagnetic forces exists when two or more objects have an electric charge like a magnet or positive and negative, negative and positive And gravitational forces is just gravity. What holds us down.
Answer:
See the explanation below.
Explanation:
<u>meters</u> per <u>second</u> per <u>second</u> = (m/s/s) = (m/s^2)
This means that the body increases or decreases its speed 1 (m/s), for every second that passes. An easy example to understand is the acceleration of gravity g = 10 [m/s^2]. This means that if a body is thrown from a 100 (m) high tower, for every second it passes the speed will increase by 10 [m/s].
To solve the problem, you should first convert the 20ft to
meters so it is much easier.
20 feet is equals to 6 meters; rounded off to the nearest
whole number.
Solution:
V1 = v
V2 = 0
T1 = ½ mv^2
T2 – 0
U 1-2 = -mgh
d = 6m
--AB^2 = (10m)^2 = d^2 + y^2 = (6m)^2 = y^2
Y^2 = 100 – 36 = 64
Y = sqrt64
h = 10 – y = 10 – sqrt64 = 10 – 8 = 2 m
U 1- 2 = -m (9.81) (2) = -19.62
T1 + U1-2 = T2
1/2mv^2 – 19.62m = 0
v^2 = (2) (19.62) = 39.24
Answer:
Atacama Large Millimeter/Submillimeter Array (ALMA) Observatory's primary goal is to provide a radio telescope array that will allow scientists to observe and image galaxies out to the edge of the universe, and stars and planets in their formative stages with unprecedented clarity.
