Answer: 16 squared + 63 squared = x squared
Explanation:
Hi, since we have a right triangle we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.
Replacing with the values given:
x^2 = 63^2 + 16^2
So, the correct option is
16 squared + 63 squared = x squared

Answer:
Tech B
Explanation:
Horsepower (hp) refers to a unit of measurement of power in respect of the output of engines or motors.
Horsepower is the common unit of power. It indicates the rate at which work is done.
The formula
, where rpm is the engine speed, T is the torque, and 5,252 is radians per second.
So,
Tech B is correct
Answer:
685.38 MJ
Explanation:
Given that:
mass = 10 tons = 1.0 × 10 ⁴ kg
diameter D = 10 m
radius R = 5 m
speed N = 1000 rpm
Using the formula for K.E =
to calculate the energy stored
where;


= 104.719 rad/s
Hence, the energy stored is;


= 685379310.1
= 685.38 MJ
