Answer:

velocity too will be negative

Explanation:

<u><em>If displacement is negative,is velocity negative too?</em></u>

<u><em /></u>

Velocity is the rate of the displacement of an object with time

velocity =  displacement / time

Since there is no negative timing in all cases, so in every case where the displacement is negative , then displacement will velocity will also be negative

For example,  If the displacement of an object is -30m  and the time 6 seconds

Then velocity = displacement / time

                       = -30/6

                        = -5 m/s

Answer:

An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).

How can you justify that force is transferred to lift and throw soil using shovel?<br>​
Natali [406]

Forces are needed to lift, turn, move, open, close, push, pull, and so on. When you throw a ball, you are using force to make the ball move through the air. More than one force can act on an object at the same time.

How does an atom of potassium-41 become a potassium ion with a +1 charge? 19 K 39.10
stiv31 [10]

It is very difficult for an atom to accept a proton. It can only be done under very special circumstances. So A and C are both incorrect. I don't see how D is possible. The atom does lose 1 electron, but how it gets 21 is think air.

The answer is B which is exactly what happens.

A highly volatile substance has an initial mass of 1200 g and its mass is reduced by 12% each second.
Softa [21]

Answer:

Explanation:

a) 1.00 - 0.12 = 0.88

m = 1200(0.88)^t

b) t = ln(m/1200) / ln(0.88)

c) m = 1200(0.88)^10 = 334.20 g

d) t = ln(10/1200) / ln(0.88) = 37.451... = 37 s

e) t = ln(1/1200) / ln(0.88) = 55.463... = 55 s
