Answer:
D. Malleable
Explanation:
Gold is metallic, with a yellow colour when in a mass, but when finely divided it may be black, ruby, or purple. It is the most malleable and ductile metal; 1 ounce (28 g) of gold can be beaten out to 300 square feet. It is a soft metal and is usually alloyed to give it more strength.
Answer:
1600 W
Explanation:
Power is the product of force and distance, divided by time.
P = (120 kg)(10 m/s²)(40 m)/(30 s) = 1600 kg·m²/s³ = 1600 W
Welll, yes, but only for an instant. A rock or baseball tossed straight up is accelerated by gravity, and when it reaches the very peak and starts to fall, it's velocity is zero at that instant.
Answer:
L = 4.32 m
Explanation:
Here we can use the energy conservation to find the distance that it will move
As per energy conservation we can say that the energy stored in the spring = gravitational potential energy
now we need to solve above equation for length L
