Food provide your body with

Physics
1 answer:
Levart [38]3 years ago
7 0
The food you eat every day provides the nutrients you need to survive. These food components include the macronutrients – protein, carbohydrate and fat – that offer calories as well as play specific roles in maintaining your health. Micronutrients, such as vitamins and minerals, don’t act as an energy source but do serve a variety of critical functions to ensure your body operates as optimally as possible.

An object accelerates 12.0 m/s² when a force of 6.0 newtons is applied to it.
Nimfa-mama [501]

Answer:

<h2>0.5 kg</h2>

Explanation:

The mass of the object can be found by using the formula

m =  \frac{f}{a}  \\

f is the force

a is the acceleration

From the question we have

m =  \frac{6}{12}  =  \frac{1}{2}  \\

We have the final answer as

<h3>0.5 kg</h3>

Hope this helps you

Aluminum wire 1.00 mm in radius is to be used to construct a solenoid 15.0 mm in radius so that the magnitude of the magnetic fi
Leto [7]

To solve this problem we will proceed to use the equations given for the calculation of the resistance, in order to find the radius of the cable. Once the length is found we can find the number of turns of the solenoid and finally the net length of it

The resistance of the wire is

R= \frac{\rho L}{A}

\rho= Resistivity

L = Length

A = Cross-sectional Area

That can be also expressed as,

R = \frac{\rho L}{\pi r^2}

Rearranging the equation for the length of the wire we have

L= \frac{R\pi r^2}{\rho}

L= \frac{3\Omega \pi(1*10^{-3})}{2.655*10^{-8}\Omega \cdot m}

L = 354.8m

The number of turns of the solenoid is

N = \frac{L}{2\pi r} \rightarrow Denominator is equal to the circumference of the loop

N = \frac{354.8}{2\pi(15*10^{-3})}

N = 3766

Finally the Length of he solenoid is

l = N (\phi)

Where \phi is the diameter of wire

l = N (2r)

l = (3766)(2*(1*10^{-3}))

l = 7.532m

Therefore the length of the solenoid is 7.532m

A cube made out of wood has a mass of 1.2 kg and the density of the wood is 400kg/m3.What is the length of the side of the cube?
LenaWriter [7]

Answer:

≈ 0.144 m

Explanation:

Density is mass divided by volume:

D = M / V

Solving for volume:

V = M / D

Given M = 1.2 kg and D = 400 kg/m³:

V = 1.2 kg / (400 kg/m³)

V = 0.003 m³

Volume of a cube is the side length cubed:

V = s³

Therefore:

s³ = 0.003 m³

s ≈ 0.144 m

Round as needed.

A heater has resistance of 10 ohms. It operates at 120 volts. a. What is the current through the heater?​
Natali5045456 [20]

Answer:

  I = 12 A

Explanation:

For this exercise we use the relationship that voltage is proportional to the product of current and resistance

           V = I R

            I = V / R

             

let's calculate

            I = 120/10

            I = 12 A
