Calculate the net force and the acceleration the block

Physics
1 answer:
scoray [572]3 years ago
8 0

Answer:

The net force is 20 N and the acceleration of the block is 5\ m/s^2

Explanation:

Given that,

Mass of the block, m = 4 kg

Force in right side = 30 N

Force in left side = 10 N

We need to find the net force and the acceleration of the block.

Net force = Right force - left force (as both are opposite to each other)

= 30 N - 10 N

= 20 N

Formula for net force,

F = ma

a is acceleration

a=\dfrac{F}{m}\\\\a=\dfrac{20\ N}{4\ kg}\\\\a=5\ m/s^2

Hence, the net force is 20 N and acceleration of the block is 5\ m/s^2.

Explain why materials such as plastic foam, feathers, and fur are poor conductors of heat.
Firlakuza [10]
The atoms of some materials have no free electrons in their outer orbits. These electrons are busy doing other jobs, like being shared in the orbits of two adjacent atoms. They are so closely held that it is very difficult to pull them away. Most compounds of carbon and hydrogen are like this. 

<span>Plastics, whose molecules are made from long combinations of carbon and hydrogen atoms, have few or no free electrons. This means that plastics are poor conductors of electricity (and they are also poor conductors of heat). hope that helped.</span>

A person Drove from 8am Tuesday to 5pm Wednesday. Total drive 396 miles. He have lunch for 30 min on Tuesday and sleep overnight
r-ruslan [8.4K]

Answer:

average speed = 18 miles / hour

Explanation:

Given data

drive = 396 miles

time = 8 am Tuesday to 5 pm Wednesday = 33 hours

lunch = 30 min Tuesday  + 30 min Wednesday = 60 min = 1 hour

sleep = 7 pm Tuesday to  5 am Wednesday = 10 hours

to find out

average speed

solution

we know that he take total time = 33 hours and he took rest + luch = ( 1 + 10 hours)

so total travel time is = 33 - 11 = 22 hours

so

average speed = distance / time

average speed = 396 / 22

average speed = 18 miles / hour

A child is stationary on a swing. The child is given a push by his brother to start him swinging. His brother applies a steady f
torisob [31]
The formula is M=Fd
so we have F=84N and d=0.25m
Now we just replace F and d into the formula M=84N×0.25m
And the last thing we do is calculate it
M=21Nm
