speed at end is accn of gravity x time
9.81x12=just over98.1m/s
The correct answer is B. The safety only prevents you from pulling the trigger, but does not stop the pin from striking the primer. For example, if you drop the firearm, the pin may hit the primer and fire the firearm. It is always responsible to keep the firearm pointed in a safe direction so that if this happens, no consequences come out of it.
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
Answer:
B) The lighter gases boiled off of the protoplanets closest to the sun, leaving dust and metals behind to form the inner planets.
Explanation:
Inner planets are smaller and rockier than outer gas planets,outer planets are larger,because of their lower gravity they don't attract extreme amounts of gas in their planets.The four outer planets were so far from the Sun that its winds could not blow away their ice and gases
No because it's conducting heat and when it does that it means it's hot so you would burn yourself.
