Three boxes rest side-by-side on a smooth, horizontal floor. Their masses are 5.0 kg, 3.0 kg, and 2.0 kg, with the 3.0-kg mass i

Fed [463]

Answer:25 N

Explanation:

Given

mass of 5 , 3 & 2 kg blocks lie on floor

Force on 50 N pushes the 5 kg box

$Let N_1$ be the reaction on 2 kg box therefore

$N_1=2\times a$

where a is the acceleration of the system

$N_2=$ reaction on 3 kg block by 5 kg block

$N_2-N_1=3a$

$N_2=5a$

Now for 5 kg block

$F-N_2=5a$

F=10a

$a=\frac{F}{10}=5 m/s^2$

Force exerted by 5 kg block on 3 kg block is

$N_2=5\times 5=25 N$

How do cells use food to make energy and maintain homeostasis?

vladimir1956 [14]

Homeostasis is the state of maintaining steady internal conditions by the living organisms. Cells obtain energy through the process of cellular respiration. It is a metabolic process of conversion of the biochemical energy from the nutrients into adenosine triphosphate (ATP). It also maintains the temperature of the body. The energy produced during this process is used in the cell division and repair of the cells by the breakdown of ATP and maintains homeostasis. They exchange substances with the new cells and also eliminate the wastes thereby maintaining homeostasis.

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.
