Answer:
3.9m/s² is the acceleration
Answer:
Attract
Explanation:
According to the properties of charge, the bodies having unlike charges attract each other and the bodies having like charges repel each other.
As the toy is initially electrically neutral, so as it is divided into two pieces, then according to the conservation of charge, the one piece having positive charge and the other piece having negative charge. As they are unlike charges so they attract each other.
A power meter is a device fitted to a bike that measures the power output of the rider.
Most commonly, power meters use strain gauges that deflect slightly when a force is applied. By measuring this torque and combining it with angular velocity, power (measured in watts) can be calculated.
Answer:
(1) 10^−2 m
Explanation:
The diameter of the tire of an automobile is generally expressed in centimetres; we can say that the diameter of a tire is generally about
d = 20 cm (20 centimetres)
Now we have to verify which option is closest to this value. To do that, we have to keep in mind the equivalence between metres and centimetres; in fact, we have:
This means that we can rewrite the diameter of the tire of a car as
By comparing it with the given options, we see that the closest option is
(1) 10^−2 m
which is therefore the correct answer.
