HELP ME ANSWER THIS FOR 96 POINTS PLEASE!!

The three modified Atwood's machines shown below have blocks of mass M on a frictionless surface
and hanging from a string. When the blocks are released, they accelerate.

Rank them from smallest to largest and explain why in a short paragraph using the mass terms and force.

Answer:

The correct answer is when the slope is steep.

Explanation:

The advancement of water inland is dependent on the rate at which water wears off the continental shelf and the coastal plain. The higher the amount of rainfall, and the harshness of the dry spells, the faster the rate of erosion that occurs at the coastal plain.

As the erosion increases, the coastal plain becomes steeper. The steeper the plain, the water flowing erodes the coastal plain at a faster rate. Hence the water advances farther inland faster than where the slope is gentle or gradual.

Answer:

0.5*0.8*45^2. =810J

Explanation:

KE=1/2 mv^2

Answer:

the answer is B.

Explanation:

The ball that is thrown straight up has more kinetic energy and more speed than the ball that is thrown straight down. Both balls have the same kinetic energy and speed.

The kinetic energy of a body can be determined as the energy of a moving physical system because of its motion. Work has to be done on an object to change its kinetic energy.

The kinetic energy of the moving system can be expressed as K.E. = ½mv²  where ‘m’ is mass while ‘v’ is the velocity of the object.

The potential Energy of the physical system can be described as the energy stored due to its position. The mathematical formula for the calculation of the potential energy can be expressed in the form of P.E = m×g×h where ‘g’ is the gravitational acceleration, ‘m’ is the mass and ‘h’ is the height in meters

When two identical balls are thrown from a cliff, each with the same speed. One ball is thrown straight up, and the other ball is straight down. Both balls will have the same kinetic energy as well as speed.

Answer:

Light is electromagnetic radiation that has properties of waves. The electromagnetic spectrum can be divided into several bands based on the wavelength. As we have discussed before, visible light represents a narrow group of wavelengths between about 380 nm and 730 nm.

OR

The primary properties of visible light are intensity, propagation-direction, frequency or wavelength spectrum and polarization, while its speed in a vacuum, 299 792 458 m/s, is one of the fundamental constants of nature.

Answer:

an example for applied force is

Explanation:

The applied force is the force applied to the object to either displace it or change its shape.

Answer:

G. it enables people to use pots and pans made of metal to cook food

Explanation:

Metals are known to be substances with a relative high melting point, which means that it takes a very high temperature to melt them. As used in this question, copper (Cu) and iron (Fe) at metallic elements that have high melting points.

One advantage of this property based on the options provided is that "it enables people to use pots and pans made of metal to cook food". This is because cooking food requires subjecting them to a constant temperature from a heat source e.g cooker or stove.

The material used to hold the food being cooked must possess a very high melting point to withstand the heat, hence, the importance of these metallic substances. Most pots and pans are made of steel, an alloy of iron, hence, they have high melting point.

Answer:

E = 0.4 kWh

Explanation:

Given that,

The power of a bulb, P = 40 W

Time, t = 10 hours

We need to find the energy used by the bulb. Let it is equal to E. So,

[tex]E=P\times t\\\\E=40\times 10\\\\E=400\ W-h\\\\or\\\\E=0.4\ kWh[/tex]

So, 0.4 kWh of energy would be needed.

Answer: 146,000 Wh or 146 kWh

Explanation:

65 days × 10 hours × 40 W = 146,000 Wh or 146 kWh

Answer:

The formula for calculating Density is:

= Mass / Volume

From this formula, we can say that the relationship between Mass and Density is a direct one. In other words, if mass is increasing - all else being equal - then density will increase as well.

If mass however was decreasing, density would have to decrease as well.

For example, assume 3 bricks have masses of 5kg, 10kg and 15kg. Also assume that the bricks all have the same volume of 5 m³.

Density of 5kg brick = 5 / 5 = 1 kg/m³

Density of 10kg brick = 10 / 5 = 2kg / m³

Density of 15kg brick = 15 / 5 = 3 kg /m³

Notice how density increases as mass increases and decreases when mass decreases.

Answer:

The asteroid belt is a region of our solar system, between the orbits of Mars and Jupiter, in which many small bodies orbit our sun.

Explanation:

Hope this helps!

Answer:

The asteroid belt (sometimes referred to as the main asteroid belt) orbits between Mars and Jupiter. It consists of asteroids and minor planets forming a disk around the sun. It also serves as a sort of dividing line between the inner rocky planets and outer gas giants.

Answer:

Time = 13333.33 s = 222.22 min = 3.7 h

Explanation:

The total amount of energy in two cells combined will be:

[tex]Total\ Energy = 40000\ J + 40000\ J\\Total\ Energy = 80000\ J\\[/tex]

Now, we calculate the power of the batteries:

[tex]Power = (Voltage)(Current)\\Power = (3\ V)(2\ A)\\Power = 6\ Watt[/tex]

Now, we use the following formula to calculate the time  the batteries will be able to deliver the power to the flashlight:

[tex]Total\ Energy = (Power)(Time)\\\\Time = \frac{Total\ Energy}{Power}\\\\Time = \frac{80000\ J}{6\ Watt}[/tex]

Time = 13333.33 s = 222.22 min = 3.7 h

Answer:

Net force = the difference between the forces of two directions

Net force= 60N-(30N+20N)

=60-50

Therefore Net force = 10N

Answer:

18,000 j

Explanation:

the lightbulb dissipates 5W of power

P = ΔE / Δt

rearrange to solve for energy

ΔE = PΔt

P = 5W

t =  1 hour = 60 minutes = 3600 seconds

ΔE = 5 * 3600

ΔE = 18000 J
