A young woman named kathy kool buys a sports car that can accelerate at the rate of 5.37 m/s 2 . she decides to test the car by

ohaa [14]

As the stan moves 0.94 s before with an acceleration 4.12 m/s^2

so the distance moved by it

$d = \frac{1}{2}at^2[tex]d = \frac{1}{2}*4.12*0.94^2$

$d = 1.82 m$

speed gained by the car is given as

$v = v_i + at$

$v = 4.12* 0.94 = 3.873 m/s$

now the relative speed of them is given as

$v_r = 3.873 - 0 = 3.873 m/s$

relative acceleration is given as

$a_r = 4.12 - 5.37 = -1.25$

now the distance between them is to be covered

$d = v_r * t + \frac{1}{2}a_r * t^2$

$1.82 = -3.873* t + \frac{1}{2}*1.25 * t^2$

by solving above equation we have

$t = 6.64 s$

so it will overtake after 6.64 s

What is one way that continental rifts are similar to mid-ocean ridges and what is one that they are different?

adell [148]

Explanation:

Continental rifts and mid-ocean ridges are both features of a divergent plate margin.

In both cases plates are moving away from one another. Therefore they are creating new land masses.

A continental drift like the east African rift valley is where a continent begins to pull apart or diverges.
A mid-ocean ridge is divergent margin in the ocean.

They are different in that, continental rift occurs within the continental plate that are on land.

But:

Mid-ocean ridges are in the oceanic crust in the ocean . They form the largest physiographic structure on the earth surface called the mid-ocean ridge.

Define are sources of energy

OleMash [197]

$\boxed{\sf{QUESTION:}}$

Define sources of energy

$\boxed{\sf{ANSWER:}}$

Energy is the capacity of a body to do work.

We Classify the sources of energy on the basis of:

Occurence:

Natural Sources: Natural energy sources are those which are made available to us by nature. Solar energy, wind energy, energy from water (hydro energy) are some of such natural sources of Energy.
Synthetic Sources: Synthetic energy are those that use man-made materials as sources of energy. Fir example, chemical energy, stored in the batteries, (used in calculators, watches, etc.) is a synthetic source of energy.

Physical State:

Solid: Firewood, Charcoal, coal are examples of solid fuels.
Liquid: Kerosene, Petrol & diesel are all liquid fuels.
Gas: Petroleum gas, commonly used as LPG (Liquified Petroleum Gas), & natural gas, also used CNG (Compressed Natural Gas), are examples of gaseous fuels

Availability:

Renewable: A renewable source of energy is a natural resource that can replenish itself naturally over a short period of time. Wind, sun, biomass (from plants) & hydropower (from water) are all renewable sources of energy. These arr inexhaustible natural resources.
Non-renewable: Energy sources which get us & cannot be replaced or replenished in a short period of time are called non-renewable sources of energy. These are also called exhaustible natural resources. Fossil fuels, (like petroleum, natural gas & coal), are non-renewable sources of energy.

When a substance changes from one phase to another, which of the following events occurs?

mojhsa [17]

Heat is transferred when a substance changes phases. Substances can be made to change phases by fluctuating the temperature, the pressure, or both. I hope I could help!
