Answer:
1768 N
Explanation:
We can solve the problem by using Newton's second law:
where
F is the net force acting on an object
m is the mass of the object
a is its acceleration
In this problem, we have a car of mass
m = 884 kg
And its acceleration is
Substituting into the equation, we find the net force on the car:
The object will sail away in a straight line ... continuing in the same direction it was going when the centripetal force stopped.
Question 8
Silicon is a semi-conductor that are mostly used in electronic devices. From the choices give, silicon is applicable in t<span>ransistor, integrated circuit and diode. But the best answer that suits this question is (B) integrated circuit.
Question 9
Power is the rate of doing work. It is calculated as,
Power = workdone/time taken to do that work.
In electricity, power = current </span>×voltage
From ohm's law, V=IR
Where I⇒current and
R⇒ resistance.
∴Power = I²R
= 6²×5
= 180 Watts
