The instantaneous velocity of the object is its speed and direction at that instant.
Answer:
The voltage is 2.114 V.
Explanation:
Given that,
Mass of both weights = 225 gm
Transducer sensitivity = 0.5 V/N
The first mass is located 20∘ north of east, the second mass is located 20∘ south of east,
We need to calculate the net equivalent force
Using formula of force


Put the value into the formula


We need to calculate the voltage
Using formula of voltage

Put the value into the formula


Hence, The voltage is 2.114 V.
"Average velocity" is the vector among the choices given in the question that describes <span>how fast an object moves over a long time interval. The correct option among all the options that are given in the question is the last option or the fourth option. I hope the answer has helped you.</span>
It burns when you start your car and that conducts electricity which burns it.
The collision of car 2 is more violent (because more impulse is exerted)
Explanation:
The collision which is more violent is the one in which more impulse is exchanged.
The impulse exerted by each car on the wall is equal to the change in momentum of the car:

where
m is the mass of the car
is the change in velocity
For the car 1,
m = 1000 kg
(the sign is negative because the velocity of the car has changed from 100 km/h to 0 km/h)
So the magnitude of the impulse of car 1 is

For the car 2,
m = 1200 kg

So the magnitude of the impulse of car 2 is

So, car 2 exerts a larger impulse, therefore its impact is more violent.
