A.
Newton's first law. When the bus starts, Shelly is still at rest so she resists motion. (When the bus stops, she'll jolt forward)
Water will boil faster at a higher elevation. Air pressure<span> affects the </span>temperature<span> at which </span>water boils quickly but cooking <span>times will take longer at higher </span>altitudes. This is due to a decrease in atmospheric pressure. An example would be putting an egg to boil. Water boils at lower temperature but the egg <span> involves heating a food to a certain temperature, so, cooking would take longer. </span>
Answer:
if you are trying to figure out if it is right. I believe it is right (the answer) but trust your instincts go for it.
Explanation:
A). balanced force
b). unbalanced force
There's no such thing as either of these. A group of two or more forces can be balanced or unbalanced. A single force can't be.
c). gravitational force ... doesn't cause an object to move in a circle;
Drop a stone from the roof of a tall building and watch it fall.
It goes straight down, not in a circle.
d). centripetal force ... force directed toward the center of a circle,
causes an object to move in a circle.
It’s either B or A, I hope this helps! I tried!
