You are dragging a block on a surface with friction at a steady speed of 2 m/s and exert a force of 5 N to do so. What is the fo

m_a_m_a [10]

Answer:

Friction = 5 N

Explanation:

As we know that block is moving at constant speed

So the acceleration of the block is zero

So we will have

$F_{net} = 0$

for net force to be zero

Force exerted on the object by external system must be counter balanced by the force of friction

So we have

$F_{ex} = F_f$

so we have

$F_f = 5 N$

A chemist has two compounds that do not chemically react. He thinks that by finding the right catalyst, he can get them to react

8090 [49]

Answer:

The chemist is incorrect because a catalyst increases the rate of reaction only.

Explanation:

A catalyst is a substance in the presence of which the speed of the reaction increases. It plays no role in the chemical change taking place.

Thus, if the two compounds are not chemically reacting, a catalyst wont make it happen either.

A chemical reaction occurs when atoms tend to lose or gain electrons. A catalyst has no role to play in this process.

A powered winch is used to pull a sailboat to shore. The winch uses a 900 W motor. If the motor is used for 30 s, how much work

kolbaska11 [484]

Answer:

they have given us

power = 900W

time = 30s

$p = \frac{wd}{t} \\ p \times t = wd \\ 900 \times 30 = w.d \\ 27000j$
