  • Mass=kg
  • Acceleration=m/s^2

Using Newtons second law

\\ \sf\longmapsto Force=Mass\times Acceleration

\\ \sf\longmapsto Force=kgm/s^2

\\ \sf\longmapsto Force=Newton(N)

Ede4ka [16]

Answer:

A bowling ball has a mass of 10 kilograms. A tennis ball has a mass of 0.08 kg. How much inertia does the bowling ball have compared to the tennis ball? 10 kg - 0.08 kg = 10.80 kg Since the bowling ball has more mass, naturally it has more inertia since inertia is a quantity that is solely dependent upon the mass

An 8.0-newton wooden block slides across a
yanalaym [24]
If the block is sliding at constant velocity then its speed is constant. That means it is not losing any kinetic energy. There is no friction acting and the coefficient of kinetic friction is zero. Sadly, that choice of answer is not offered.

1. Household circuits are often wired with two different widths of wires: 12-gauge and 14-gauge. The 12-gauge wire has a diamete
Jet001 [13]

Answer:

This formula R =ρL/A

Where R = resistance of wire, ρ = resistivity of the wire and A = area of the wire. Shows there is an inverse relationship between Resistance and Area of the wire.

Explanation:

A simple way to explain the physics behind such an electrical code is to compare the flow of current through wires to the flow of water through pipes, they are similar in any respect. The resistance to the flow of current in an electric circuit is similar to the frictional experienced by water when flowing through water pipes. Just as water will flow easily with little resistance through a water pipe with the larger cross-sectional area than one with a smaller cross-sectional area, in the same way, wires with larger cross-sectional area will allow the flow of larger amount of current compared to wires with smaller cross-sectional area assuming all other variables are the same.

From the formula R =ρL/A

Where R = resistance of wire, ρ = resistivity of the wire and A = area of the wire

We can see that the resistance and area of the wire have an inverse relationship. An increase in the area of the wire will lead to a decrease in the resistance of the wire.

A point charge of 4.0 µC is placed at a distance of 0.10 m from a hard rubber rod with an electric field of 1.0 × 103 . What is
yuradex [85]
Since

Electric potential energy = qV

Where V = Ed

Hence
Electric potential energy = q(Ed) --- (1)

Since E = 1.0 * 10^3 N/C
d = 0.10 m
q = 4 * 10^-6 C

Plug in the values in (1)
(1) => Electric potential energy =  4 * 10^-6(1.0 * 10^3 * 0.10)
Electric potential energy = 400 μJ

After a while, the car started to go around a long bend, still maintaining its constant speed of 55 miles per hour. Is there a n
sukhopar [10]

Answer:

4) True. The change of direction needs an unbalanced force

Explanation:

Let us propose the resolution of the problem using Newton's second law.

    F = m a

As the car is spinning the acceleration is centripetal

    a = v2.r

   

    F = m v2 / r

We can see that as the velocity of a vector even if its module does not change, the change of direction requires an external force.

Now we can analyze the statement if they are true or false

1) and 3) False, even when the speed changes, the direction changes

2) False with the speed change can be determined

4) True. The change of direction needs an unbalanced force

5) False are different things. the direction is where it is going and the speed is the magnitude of the vector
