Answer:

Muscular Force = Uses when walking

The Force of wind = Force used to turn a windmill

Force of Gravity = Used to drag thing to the centre of the earth

Steam = Type of force used to operate machines

Work = Amount of force Times the distance moved

Foot - Pound = Moving one pound one foot

Newton meter = moving one newton one meter

Alona [7]

Answer:

Explanation:

This does not violate Newton's 1st law because the net force would still be 0 in order to produce uniform motion (aka constant velocity). The other forces acting on the vehicles is air resistance which is non-zero. So we need car internal force to counter balance this force, which require extra gas for the car.

Give reason Pascal is a derived unit​
Stells [14]

Answer:

Pascal is a derived unit because <u>it</u><u> </u><u>cannot</u><u> </u><u>be</u><u> </u><u>expressed</u><u> </u><u>in</u><u> </u><u>any</u><u> </u><u>physics</u><u> </u><u>terms</u><u>,</u><u> </u><u>but</u><u> </u><u>it</u><u> </u><u>is</u><u> </u><u>an</u><u> </u><u>expression</u><u> </u><u>of</u><u> </u><u>fundamental</u><u> </u><u>quantities</u><u>.</u>

Explanation:

{ \sf{Pasacal \: ( Pa) =  \frac{newtons}{metres {}^{2} } }} \\  \\ { \sf{Pasacal  \: (Pa) =  \frac{kg \times  {ms}^{ - 2} }{ {m}^{2} } }}

Change 6 revolutions per minute to a linear speed measured in m/s. The radius is 3 m.
satela [25.4K]

Answer:

Explanation:you know

circumference of a circle =2*pi*r=?

r=radius of a circle =3m

total distance of 6 revolution =s=6*2*pi*r

again, linear speed =v=s/t=?

t=time =60sec

7. A spring balance reads force in Newton. The scale is 20 cm long and reads from 0 to
GarryVolchara [31]

Answer:

The potential  energy when it reads 40 N is PE  = 5.33 \ J

Explanation:

From the question we are told that

   The lowest reading of the spring balance is  0 N and this is at  0 cm = 0 m

   The height reading of the spring balance is 60 N  and this is at 20 cm =  0.20 m

   Generally the length corresponding to the reading of 40 N is mathematically represented as

       d = \frac{40 * 0.20 }{60 }

=>    d = 0.133 \  m

Generally the potential  energy is mathematically represented as

      PE = m * g * d

Here

     F = mg  =  40 N

So  

     PE = 40 * 0.133

=>  PE  = 5.33 \ J
