Whats the difference between speed and velocity of an object

Physics
1 answer:
ss7ja [257]3 years ago
4 0
The difference between speed and velocity is that the speed is a scalar quantity which means that you can say that this object has a speed of x m/s but you don't have to define its direction
while the velocity is a vector quantity which means that you have to express the velocity by which it moves in x,y and z directions and its norm is the speed

grigory [225]
<span>The answer is transformer. They utilize electromagnetic induction to generate current. This is only possible in alternating current due to the differential increase and decrease of electrical current that induces changes in magnetic flux in the coil. This varies the magnetic flux of the primary coil that generates current in the secondary coil.</span>

A subtence floats or sinks in onother becauseof its relitivity
Helga [31]
No.  A substance floats or sinks in another substance because of
the densities of both of them.

If the density of the substance is more than the density of the other
one, it will sink.  If less than the density of the other one, it will float.

Your roommate drops your wallet down to you from the third-floor window of your apartment, which is 11.5 m from the ground. What
Aneli [31]

Answer:

15 m/s

Explanation:

Using the law of conservation of energy, potential energy equals kinetic energy hence

mgh=0.5mv^{2}

Therefore

v=\sqrt{2gh}

where g is the acceleration due to gravity, m is the mass of the object, h is the height and v is the speed of the wallet

Taking g as 9.81 then

v=\sqrt{2\times 9.8\times 11.5}=15.02098532  m/s\approx 15 m/s
