Sample Response: If force is applied to a car, then its acceleration will change proportionally, as predicted by Newton’s second law, F = ma.

Answer:

F=ma is the relationship where, F is force, m is mass and a is acceleration.

Newton's second law states that  the unbalanced force applied to the object accelerates the object which is directly proportional to the force and inversely to the mass.

If we apply force to a toy car then It will accelerate.

This is how Newton's second law of motion is verified.

Answer:

When an object is heated it Expand and when it cools it Contract

Explanation:

One of the effect of heat on matter is expansion. An increase in the temperature of an object causes it to expand and a decrease causes it to contract

A proton is launched from an infinite plane of charge with surface charge density -1.10×10-6 C/m2. If the proton has an initial
Katyanochek1 [597]

The distance covered by the proton is 48.4 m

Explanation:

The electric field produced by an electrically charged infinite plane is given by

E=\frac{\sigma}{2\epsilon_0}

where in this case,

\sigma = -1.10\cdot 10^{-6} C/m^2 is the surface charge density

\epsilon_0 = 8.85\cdot 10^{-12} F/m is the vacuum permittivity

Substituting,

E=\frac{-1.10\cdot 10^{-6}}{2(8.85\cdot 10^{-12})}=-5.65\cdot 10^4N/C

And the direction is towards the plane (because the charge is negative).

The electric force on the proton due to this field is

F=qE

where

q=1.6\cdot 10^{-19}C is the proton charge

Substituting,

F=(1.6\cdot 10^{-19})(-5.65\cdot 10^4)=-9.0\cdot 10^{-15} N

where the direction is toward the plane.

Now we can calculate the proton's acceleration using Newton's second law:

a=\frac{F}{m}

where

m=1.67\cdot 10^{-27}kg is the proton mass

Substituting,

a=\frac{-9.0\cdot 10^{-15}}{1.67\cdot 10^{-27}}=-5.4\cdot 10^{-12} m/s^2

Now we can finally apply the following suvat equation for accelerated motion to find the distance travelled by the proton:

v^2-u^2=2as

where

v = 0 is the final velocity

u=2.40\cdot 10^7 m/s is the initial velocity

a is the acceleration

s is the distance covered

And solving for s,

s=\frac{v^2-u^2}{2a}=\frac{0-(2.4\cdot 10^7)^2}{2(-5.4\cdot 10^{12})}=53.3 m

Therefore, the closest answer is 48.4 m.

marin [14]
Using conservation of momentum, we can solve for the force that the air bag exerts on the person.

Recall the equation for momentum (p):

p = mv = F*dt

We can solve for total momentum, then divide by out time interval. This gets us:

(60kg)(16m/s) = F(0.2s)


F = 4800N

F = 4800N
