The appropriate PPE(personal protective equipment) to be worn for foot protection against electric shock is boots retrofitted with rubber soles. Rubber does not conduct electricity and so will safeguard against electric shocks.
Other personal protective equipment used in a lab or industry can include safety glasses, rubber gloves, protective clothing and masks and respirators. PPE goes hand in hand with personal behaviour, personal grooming and housekeeping.
Given Information:
Mass of elephant = m = 750 kg
Height = h = 14.3 m
time = t = 30 seconds
Required Information:
Power needed to lift elephant = P = ?
Answer:
Power needed to lift elephant ≈ 3507 watts
Explanation:
As we know power is given by
P = PE/t
Where PE is the potential energy and t is the time
Potential energy is given by
PE = mgh
Where m is the mass of elephant, g is the gravitational acceleration and h is the height to lift the elephant.
PE = 750*9.81*14.3
PE = 105212.25 Joules
Therefore, the required power to lift the elephant is
P = PE/t
P = 105212.25/30
P ≈ 3507 watts
Answer:
C
Explanation:
because warm air is less dense, and warm air rises and cold air sinks. (did research) hope this helps!! :)
Answer = 6.24x10^18 x ((2 x 3600) + (47 x 60) + 10)
