Answer:

Chemical energy

Explanation:

The energy held in the foods molecules a lunch pack is composed of is chemical energy.

They occur within food substances which originates from plants and animals as giant organic molecules.

Since food is often derived from plants and animals.
Plants produce their own food by producing macromolecules from simple inorganic substances in the environment.
Animals takes up these food and build their own body through it.
Plants and animal parts constitutes organic molecules in which chemical energy is duly stored.
When the molecules are broken down, they released their chemical potential energy into heat energy.

Find the moment of inertia Ihoop of a hoop of radius r and mass m with respect to an axis perpendicular to the hoop and passing

Juliette [100K]

Answer: MR²

is the the moment of inertia of a hoop of radius R and mass M with respect to an axis perpendicular to the hoop and passing through its center

Explanation:

Since in the hoop , all mass elements are situated at the same distance from the centre , the following expression for the moment of inertia can be written as follows.

I = ∫ r² dm

= R²∫ dm

MR²

where M is total mass and R is radius of the hoop .

A car has a force of 2000N and a mass of 1000kg. What is the acceleration

Anastaziya [24]

Answer:

2m/s/s

Explanation:

The formula goes- F=MA

F-Force M-Mass & A-Acceleration

We need to rearrange this formula to find the acceleration-

A=F/M

All we need to do now is substitute the values in

A=2000N/1000kg

A=2m/s^2

In the given option the last option (2m/s/s) would be the ans, as it's the same as 2m/s^2

So ya, I guess that's all

A uniform electric field is produced due to the charge distribution inside the closed cylindrical surface. (a) What type of char

DiKsa [7]

Answer with Explanation:

a. Option d is true.

a negatively charged plane parallel to the end faces of the cylinder

b. Radius of cylinder, r=0.66m

Magnitude of electric field, E=300 N/C

We have to find the net flux through the closed surface.

Net electric flux, $\phi=-2 EA=-2E(\pi r^2)$

$\phi=-2\times 300\times (3.14\times (0.66)^2)$

$\phi=-820.67 Nm^2/C$

Net charge, $Q=\epsilon_0\times \phi$

Where

$\epsilon_0=8.85\times 10^{-12}$

$Q=-820.67\times 8.85\times 10^{-12}$

$Q=-7.26\times 10^{-9} C$

$Q=-7.26nC$

Where $1nC=10^{-9}C$

A 79.7 kg base runner begins his slide into second base while moving at a speed of 4.77 m/s. The coefficient of friction between

SashulF [63]

To solve this problem we will apply the concept related to the kinetic energy theorem. Said theorem states that the work done by the net force (sum of all forces) applied to a particle is equal to the change experienced by the kinetic energy of that particle. This is:

$\Delta W = \Delta KE$
