On a trip you travel at a constant speed of 25 kilometers per hour South for 1 hour. You then turn West and travel at a constant speed of 50 kilometers per hour for 2 hour. Calculate your velocity for the trip.

Answer:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

Explanation:

hope it help mark me as brill please

Answer:

acceleration equals the change in velocity divided by time

Answer:

* the two plates of the same sign  E = 0

* the two plates of different sign    E/e = 2

Explanation:

In this exercise, the relationship between the field created by a plate and two infinite plates is asked.

The electric field created by each plate has the value of "e", which is related to the charge on the electric plate.

                 e = [tex]\frac{ \sigma }{2 \epsilon_o}[/tex]

If the plate is negative the electric field is directed towards the plate and if the plate is positive the electric field is directed out of the plate.

The test charge is always positive.

When we have two plates, we have several possibilities

* the two plates of the same sign

therefore the resulting electric field on the test charge is

              E_total = e - e

              E = 0

* the two plates of different sign

              E_total = e + e

               E = 2 e

the relationship between the two fields is

             E/e = 2

Answer:

248 minutes

Explanation:

6200/25=248

This means there is 248 25s in 6200

which means it will take 248 minutes to travel through the river

Also here's a neat trick:

The units for speed is meters/minute

The units for distance is meters

Dividing distance by speed will cancel out the meters and leave only the speed.

Answer:

Explanation:

Inertia is the property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity.

The more mass, the more inertia. If you increase the mass of the object then you increase the inertia.

answer : Conduction, Lattice vibration  ( B )

Explanation:

The thermal transfer of energy occurs in a solid like a copper rod following two process therefore the second process and method are

Lattice vibration  and  conduction

Lattice vibration is the movement/oscillation of atoms in a solid and this is caused by the change/increase in temperature applied to the solid and these vibrations will lead to the thermal transfer of energy via conduction since the atoms are bounded together .

An engine made of heat!

Okay actual answer, A heat engine is a mechanical energy converter that transforms heat or thermal energy to mechanical energy.

Answer:

0.4m/s

Explanation:

[tex]F = ma[/tex] where F= force, m= mass, and a=acceleration

we also know that,

a = Δv / t where Δv = change in velocity and t = time

thus F = m ( Δv / t)

[tex]2000=50(\frac{v}{0.01})[/tex]

[tex]\frac{2000}{5000} = v[/tex]

0.4m/s = Δv

Answer:

flux melting

Explanation:

Flux melting is the process that causes magma to form. Flux melting happens when water or carbon dioxide exists added to rock.

When rock is exposed to water or carbon dioxide, flux melting occurs. The rock melts at lower temperatures as a result of these substances. This causes magma to form where it had a solid structure before. Around subduction zones, flux melting also happens, much like heat transfer.

Flux melting happens in igneous petrology and volcanology when water and other volatile substances are added to hot solid rock, depressing the solidus. Flux is a material, such as salt, that produces a mixture with a metal oxide that has a low melting point (liquidus) in engineering and metallurgy.

1. Ultraviolet light (UV)

2. X-rays

3. Gamma-rays

Explanation:

Though there are different types of energy or electromagnetic waves with varying wavelengths, including the likes of Gamma X-rays, ultraviolet light, visible light, infrared radiation, and microwave radiation.

What is more certain is that the atmosphere blocked the high-energy waves from getting to the earth surface or biosphere such as Ultraviolet light (UV), X-rays and Gamma-rays

Ok so it is working ok!

Answer:

remember the ways in which the heat is transferred:

Conduction: Heat transfer of two objects touching.

Convection: Heat transfer in a medium with a gradient of temperature.

Radiation: Heat transferred between two objects that not touch each other (an example of this is how the Sun heats up the Earth)

First, we start with the gas itself.

It has a lot of pressure, so when you open the knob, the gas can get out.

The has chemical potential energy.

When you combust the gas, you transform that energy into heat energy, as the flame touches the pot, it starts o also heat the pot.

This heat energy is transferred to the pot, which transfers heat energy to the water by conduction, the heat in the water is "distributed" by convection, and as the water starts to heat up, the energy is transferred to the egg by conduction.

Answer:

1840 J

Explanation:

From the question given above, the following data were obtained:

Specific heat capacity (C) = 0.46 J/gºC

Mass (M) = 50 g

Initial temperature (T₁) = 20 °C

Final temperature (T₂) = 100 °C

Heat (Q) required =?

Next, we shall determine the change in the temperature. This can be obtained as follow:

Initial temperature (T₁) = 20 °C

Final temperature (T₂) = 100 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 100 – 20

ΔT = 80 °C

Finally, we shall determine the heat required. This can be obtained as follow:

Specific heat capacity (C) = 0.46 J/gºC

Mass (M) = 50 g

Change in temperature (ΔT) = 80 °C

Heat (Q) required =?

Q = MCΔT

Q = 50 × 0.46 × 80

Q = 1840 J

Thus, 1840 J of heat energy is required.

Answer:

Pumping a well lowers the water level around the well to form a cone of depression in the water table. If the cone of depression extends to other nearby wells, the water level in those wells will be lowered. The cone develops in both shallow water-table and deeper confined-aquifer systems.
