Answer:
Power input, P = 2880 watts
Explanation:
It is given that,
Voltage of the motor, V = 240 V
Current required, I = 12 A
Weight lifted, W = 2000 lb
It is lifting at a speed of 25 ft/min. We need to find the power input to the motor. The product of current and voltage is called power input of the motor.


P = 2880 watts
So, the power input of the motor is 2880 watts. Hence, this is the required solution.

Answer:
area = 5733.33  cm²
length = 5.47 × cm
 cm
Explanation:
Given data 
density = 19.32 g/cm³
mass = 33.16 g
thickness = 3.000 µm = 3 × cm
 cm
radius r = 1.000 µm = 1 × cm
 cm
to find out 
area of the leaf and  length of the fiber
solution
we know volume formula that is
volume = mass / density
volume = 33.16 /  19.32 
volume = 1.72 cm³
we know that volume = thickness × area
so area
area = volume / thickness 
area = 1.72 / 3 ×
area = 5733.33  cm²
and
we know volume = πr²L
so L = volume /  πr²
length = 1.72 / π(1× )²
)²
length = 5.47 × cm
 cm
 
        
             
        
        
        
Given the time, the final velocity and the acceleration, we can calculate the initial velocity using the kinematic equation A: 
 
A skateboarder flies horizontally off a cement planter. After a time of 3 seconds (Δt), he lands with a final velocity (v) of −4.5 m/s. Assuming the acceleration is -9.8 m/s² (a), we can calculate the initial velocity of the skateboarder (v₀) using the kinematic equation A.

Answer:
-273°C = Absolute zero
Explanation:
Average Kinetic energy of particles in matter refers to the temperature of matter. This value is not arbitrary zero temperature. It explains the lowest kinetic energy of the particles in matter.
