How long is the ball in the air?
Round the answer to two significant digits
Answer:
The correct answer is t = 0.92s
Explanation:
Initial velocity v0 = 3.0 m/s
Displacement Δy = ?
Acceleration a = -9.8m/s2
Final velocity v = -6.0m/s
Time t=? Target unknown
We can use the kinematic formula missing Δy to solve for the target unknown t:
V=v0+at
We can rearrange the equation to solve to t:
V-v0=at
t= v-v0/a
Substituting the known value into the kinematic formula gives:
t= (-6.0m/s)-(3.0m/s)
————————————
-9.8m/s2
= -9m/s
—————-
-9.8m/s2
=0.92s
Sarah throws a ball directly upward at the edge of a cliff with a starting velocity of 3.0 m/s. It lands on the ground with a final speed of 6.0 m/s.
How long is the ball in the air?
Answer: 0.92
B: direction and distance
C: position and rate
D: distance and mass
please help which one are these . for science class
Answer:
Explanation:
D Distance and Mass
The correct answer is B) Conductor
A conductor is a material that allows for the flow of electrical charge (electrical current). This type of material provides little or no resistance to the flow of electric current. This is due to the fact that these type of materials have free electrons which conduct the flow of electrical current in any direction.
Different types of conductors have different resistances. Some types of materials are good conductors whereas some are not so good.
Some common conductors are Copper, gold, silver and aluminium.
An insulator is the an object of type of material which have a strong resistance to the flow of electric current. Some common insulators are glass, wood and plastic.
Answer:
weight will decrease
Explanation:
this is because mad stays the same no matter what so it was between this and weight increases
Answer:
Its weight will decrease.
Explanation:
just because
Explanation:
This is true that being rejected by a peer group can negatively influence one's self-esteem.
This is because when a person gets rejected then he himself develops an image that there might be something bad in me that is why people don't like me.
And when this rejection exceeds to an extent then there might be possibility that the person will become irritated and arrogant. Then he must be willing that whatever he wants he should have it no matter if it is legal or illegal according to him.
So, basically reject from people can lead to hatred, negative feelings, disappointment or dejection into a person.
B.the source of energy that fuels stars
C.the expansion of the universe
D.the origin of life
E.what came before the big bang
Answer: A.unexpected orbital velocities of stars in galaxies
Explanation:
Dark Matter makes up about 80% of matter in the universe. This matter does not emit light and hence, it is called dark matter as it cannot be observed directly.
The effect of the presence of the dark matter is unexpected orbital velocities of stars in galaxies. At the center, the orbital velocities are greater than those at the edge. Had there been no dark matter, the galaxy would have flown apart.
