Organelles are small structures found in cells that carry out certain tasks. Two examples of organelles are the Nucleus and the Mitochondria. Think of the nucleus as the brain of its cell, it controls activities and it contains a majority of the cells genetic material. The mitochondria is the part of the cells tasked with cellular respiration, which is the act of taking nutrients from a cell and turning it into energy.

A student sits atop a platform a distance h above the ground. He throws a pingpong ball horizontally with a speed v. However, a
Nikitich [7]

Answer:

Explanation:

The pingpong ball reaches the ground directly under the student. That means net displacement is zero

Time of fall  t = \sqrt{\frac{2h}{g} }

Initial horizontal velocity = v ,

horizontal acceleration = - a ( deceleration because net displacement is zero)

0 = ut - 1/2 a t²

0 = v\times\sqrt{\frac{2h}{g} } - \frac{1}{2}a \frac{2h}{g}

v = 1/2 a \sqrt{\frac{2h}{g}

h = \frac{2gv^2}{a^2}

What effect does Earth’s spherical shape have on the amount of sunlight that reaches the equator?
vaieri [72.5K]

A

Explanation:

The earth is spherical. So it's middle part is bulgjng outside. So more sunlight will be incident on the latitude near the equator. This will heat the air and it will rise up. This will cause high pressure difference and polar disturbances.

I hope this satisfies you. I hope u will follow me and make this the brainliest answer.

Phantasy [73]

Force equals mass time acceleration. Weight is a force and it can replace force in the equation. The acceleration would be gravity, which is an acceleration.

1.)

Fw (weight) = m (mass) · g (gravity, 9.8 m/s²)

Fw = m * 9.81 m/s²

560N = m · 9.81 m/s²

m ≈ 57.08 kg

2.)

d = 350 meters

t = 65 seconds

velocity = d/t

velocity = 350 meters / 65 seconds

velocity ≈ 5.38 meters/sec

3.)

Force = 35N

Distance = 2 meters

Work = Force · Distance

Work = 35N · 2 meters

Work = 70 J
