A person is trying to lift a crate that has a mass of 30 kg. The normal force of the floor is currently supplying 150 N of force
2 answers:
Answer:
The exerting force by the person is 294 N.
(3) is correct option.
Explanation:
Given that,
Mass of crate = 30 kg
Normal force = 150 N
When a person is lifting a crate then the crate does not contact the floor
So, the normal force is zero.
We need to calculate the exerting force by the person
Using formula of force
Hence, The exerting force by the person is 294 N.

Answer:
Q = 5 L/s
Explanation:
To find the flow you use the following formula (para calcular el caudal usted utiliza la siguiente formula):
V: Volume (volumen) = 200L
t: time (tiempo) = 40 s
you replace the values of the parameters to calculate Q (usted reemplaza los valores de los parámteros V y t para calcular el caudal):
Hence, the flow is 5 L/s (por lo tanto, el caudal es de 5L/s)
