eaves aren’t wilted any longer. Why did this happen?
A) The xylem stored the water in the stem of the plant, making it more rigid


B) The water flowed out of the vacuole creating turgor pressure in the plant’s cells


C) The plant’s stored energy was activated by the water


D) The water entered the vacuole creating turgor pressure in the plant’s cells

A ball is thrown straight up into the air. At each of the following instants, is the ball's acceleration ay equal to g, −g, 0, g
Leto [7]

Answer:

a= (-g) from the moment the ball is thrown, until it stops in the air.

a = (0) when the ball stops in the air.

a = (g) since the ball starts to fall.

Explanation:

The acceleration is <em>(-g)</em> <em>from the moment the ball is thrown, until it stops in the air</em> because the movement goes in the opposite direction to the force of gravity. In the instant <em>when the ball stops in the air the acceleration is </em><em>(0)</em> because it temporarily stops moving. Then, <em>since the ball starts to fall, the acceleration is </em><em>(g)</em><em> </em>because the movement goes in the same direction of the force of gravity

a satellite maintains an orbit equidistant from the earth at all points along its orbital path hiw is the satellite affected by
Paraphin [41]
ANY closed orbit exists because of the centripetal force of gravity.
Without the force of gravity, the satellite would simply sail away
in a straight line.

The orbit you're describing happens to be a circular orbit, but it
doesn't have to be circular.

If a net force of 800n is acting on an object with a mass of 60kg. What would be the objects accelerations
aivan3 [116]

Answer: 13.33 m/s^2

Explanation:

Force is the product of mass of an object and its acceleration.

i.e Force = Mass x Acceleration

Since Force on object = 800N

Mass of object = 6Kg

Acceleration = ?

Then, Force = Mass x Acceleration

800N = 60Kg x Acceleration

Acceleration = (800N/60kg)

Acceleration = 13.33 m/s^2 (The unit of acceleration is metre per second square)

Thus, the objects accelerations is 13.33 m/s^2

One strategy in a snowball fight is to throw
Oxana [17]

second question: How many seconds after the first snowball

should you throw the second so that they

arrive on target at the same time?

Answer in units of s.

Answer:

Part 1: 28°

Part 2: 1.367

Explanation:

Part 1:

Given: 62°  

Simple

θ = 90°- 62°

<u>θ = 28°</u>

Part 2:

Y-direction

Δy=v_{yo} t+\frac{1}{2} a_{y} t^{2}

0=[16.2sin(62)]t_{1}+1/2(-9.8)t_{1}^{2} \\

t_{1} =\frac{2[16.2sin(62)]}{9.8}

t_{1}=2.91913s

0=[16.2sin(28)]t_{2}+1/2(-9.8)t_{2}^{2}

t_{2} =\frac{2[16.2sin(28)]}{9.8}

t_{2}=1.55213s

Δt=t_{1}-t_{2}

Δt=2.91913-1.55213

<u>Δt= 1.367s</u>

Hope it helps :)

If you increase the frequency, what happens to the velocity of the wave?
STALIN [3.7K]

Answer:

Wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. ... Rather, the speed of the wave is dependent upon the properties of the medium such as the tension of the rope.
