An 80 kg diver jumps from a 10 m high platform. What is the gravitational potential energy of the diver right before they jump (top of platform)

Answers

Answer:

0 Joules.

Explanation:

Given the following data;

Mass = 80kg

Height = 10m

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

[tex] G.P.E = mgh[/tex]

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

We know that acceleration due to gravity is equal to 9.8m/s²

But since we're determining the gravitational potential energy just before the driver jump, the height would be zero (0) meters.

Gravitational potential energy= mgh

Gravitational potential energy = 80*9.8*0

Gravitational potential energy = 0 Joules.

This ultimately implies that, if an object or body hasn't moved (jumped) from its reference point, its gravitational potential energy would be equal to zero.

A car covers 400m distance in 50 sec find it's speed?

Answers

Answer:

[tex]\boxed {\boxed {\sf 8 \ m/s}}[/tex]

Explanation:

Speed is equal to distance over time.

[tex]s=\frac{d}{t}[/tex]

The distance is 400 meters and the time is 50 seconds.

[tex]d= 400 \ m \\t= 50 \ s[/tex]

Substitute the values into the formula.

[tex]s=\frac { 400 \ m }{ 50 \ s}[/tex]

Divide.

[tex]s= 8 \ m/s[/tex]

The speed of the car is 8 meters per second.

Mosa believes that ocean currents help to regulate the climate of the earth. Explain why.

Answers

Answer:

Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth's land would be habitable.

Ocean currents help to regulate the climate of the earth as it transports warm water  from the equator to the polar region and carry cold water from poles back towards the equator .

What is an ocean currents ?

An ocean current is a continuous , directed movement of sea water generated because wind , breaking waves , temperature , salinity differences etc .

Ocean currents that move from north to south ,transports warm water  from the equator to the polar region and carry cold water from poles back towards the equator .  This is  how ocean currents help to counteract the uneven distribution of solar radiation  , without ocean current it would be really hot in equator and really cold at poles.

A zebra drinks from a watering hole and is ambushed by a crocodile. What's more important and why: the zebra having a high maximum speed or a high acceleration?

Answers

Answer:

before this type of attack, high acceleration is the most important thing.

Explanation:

As the zebra is ambushed by the crocodile the most important thing is a quick reaction, in this attack the most likely is that the crocodile is in the water so it cannot run after the zebra.

Consequently, before this type of attack, high acceleration is the most important thing.

B. They move matter easily
C. They do not lose energy over long distances.
D. Informatioŋ can be encoded in the wave speed.

Answers

I believe the answer is C or A but I’m not sure

One reason that electromagnetic waves are used in long-distance communication is, that they do not lose energy over long distances. So Option C   is correct

What are electromagnetic waves ?

Electromagnetic waves are a type of wave that consists of oscillating electric and magnetic fields. They are propagated through space or through a material medium, and they have the ability to travel through a vacuum, which is the absence of matter. Electromagnetic waves have a wide range of frequencies, which determines the type of electromagnetic wave. The most familiar types of electromagnetic waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

One of the property of the electromagnetic waves is that they do not lose energy over long distances.

a) What average acceleration is required to accomplish this?
b) If the mass of the rocket + fuel is 3.05x105 kg, what is the applied force of the engine?

Answers

A) average acceleration = final velocity - initial velocity / time

= 7700 - 0 / 11

= 700ms^-2


B) force = mass x acceleration

= (3.05 x 105) x 700

= 320.25 x 700

4.00 kg glass coffee cup is 30.0°C at room temperature. It is then plunged into hot dishwater at a temperature of 90.0°C, as shown in Figure below. If the temperature of the cup reaches that of the dishwater, how much heat does the cup absorb? C glass = 837 (J/kg.C)*

Answers

Answer:

Q = 200800 Joules.

Explanation:

Given the following data;

Mass = 4kg

Initial temperature = 30.0°C

Final temperature = 90.0°C

Specific heat capacity of glass = 837 J/kg°C

To find the quantity of heat absorbed;

Heat capacity is given by the formula;

[tex] Q = mcdt[/tex]

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

dt = T2 - T1

dt = 90 - 30

dt = 60°C

Substituting the values into the equation, we have;

[tex] Q = 4*837*60[/tex]

Q = 200800 Joules.

Therefore, the amount of heat absorbed is 200800 Joules.
