What is the main cause of twice-daily tides around the world?<br><br><br> Help me.
liraira [26]

<em>The main cause of twice-daily tides around the world are;</em>

Gravitational pull of the moon

<u>Tides are the rise and fall of water caused by gravitational forces of the moon and sun on the oceans of the earth. </u>

<u>The moons gravity is large enough to actually pull water out of the ocean from space. Just enough to create motion of the tides.</u>

A disk-shaped merry-go-round of radius 2.93 m and mass 165 kg rotates freely with an angular speed of 0.691 rev/s . A 62.4 kg pe
vekshin1

Answer:

Explanation:

The problem is related to rotational motion . So we shall find out rotational kinetic energy .

K E = 1/2 x I ω²

ω is the final angular velocity

Moment of inertial of the disk

I ₁ = 1/2 m r²

= .5 x 165 x 2.93²

= 708.25 kgm²

Moment of inertial of the person

I₂ = mr²

= 62.5 x 2.93²

= 536.55 kgm²

ω₂ = v / R

= 3.11 / 2.93 rad /s

At the time of jumping , law of conservation of angular momentum will apply

I₁ ω₁ + I₂ω₂ =  (I₁  + I₂)ω

708.25 x0.691 + 536.55 x ( 3.11 / 2.93 ) = ( 708.25 + 536.55 ) ω

ω = 0  .85 rad/ s

K E = 1/2 x I ω²

= .5 x ( 708.25 + 536.55 ) ( .85 )²

449.68 J

Find the mass. 10 points. Will give brainliest.
TiliK225 [7]

Answer:

<h2>3.94 kg</h2>

Explanation:

Given,

Force ( f ) = 30 N

Acceleration(a) = 7.6 m/s

Now, Let's find the mass of the ball

Using the Newton's second law of motion:

We get:

force \:  = mass \:  \times acceleration

plug the value

30 \:  = m \:  \times 7.6

Use the commutative property to reorder the terms

30 = 7.6 \: m

Swap the sides of the equation

7.6m = 30

Divide both sides of the equation by 7.6

\frac{7.6 \: m}{7.6}  =  \frac{30}{7.6}

Calculate

m = 3.94 \: kg

Hope this helps..

Best regards!!
