Calculate the force of an object shot in the air with a mass of 2 kg and an acceleration of 9.81 m/s2.
Helen [10]

Answer:

Force = 19.62 Newton

Explanation:

Given the following data;

Mass = 2kg

Acceleration = 9.81 m/s²

To find the force;

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

Substituting into the formula, we have;

Force = 2 * 9.81

Force = 19.62 Newton

At one instant of time, a car and a truck are traveling side by side in adjacent lanes of a highway. The car has a greater veloc
Helen [10]

Answer:

NO

Explanation:

Acceleration is change in velocityΔv in respect to timeΔt

so if the velocity of the car is greater than the truck it does not mean that the car acceleration is greater than the truck.

Sometimes with constant velocity it means no accelaration ,but the truck may have accelaration

so, higher velocity of the car does not mean higher acceleration

Calculate the change in momentum of a ball has 35 kg mass and it changed its velocity from 3m/s to 6 m/s
inessss [21]

Answer:

105 kg.m/s

Explanation:

Formula for change in momentum is given as;

ΔP = m(v - u)

We are given;

Mass; m = 35 kg

Initial velocity; u = 3 m/s

Final velocity; v = 6 m/s

Thus;

ΔP = 35(6 - 3)

ΔP = 35 × 3

ΔP = 105 kg.m/s

A voltage source is connected across two 1 kohm resistors in parallel. The current flowing through the voltage source is measure
victus00 [196]

Answer:

<em>1 Volt</em>

<em></em>

Explanation:

The resistors have resistance R = 1 kΩ each = 1 x 10^3 Ω each

The current through the voltage source I= 2 mA = 2 x 10^-3 A

The resistors are in parallel, son the total resistance will be

\frac{1}{R_{T}} = \frac{1}{R_{1}}  + \frac{1}{R_{2}}

\frac{1}{R_{T}} = 1/1 kΩ  + 1/1 kΩ

\frac{1}{R_{T}}  = 2/1 kΩ

R_{T} = 1 kΩ ÷ 2 = 0.5 kΩ = 500 Ω

From V = IR

where V is the voltage

I is the current

R is the resistance

substituting, we have

V = 500 x 2 x 10^-3 =<em> 1 V   This is the voltage across each resistor</em>

In a gasoline engine,__<br>energy is converted into kinetic energy.<br><br>is it thermal?​
12345 [234]

It might be possible to argue for "thermal", but it would be tough.

A much better answer is "chemical" ... the engine runs on the chemical energy stored in the gasoline.
