Newton’s Second Law

Unbalanced forces

When the forces acting on an object do not balance, the resultant force will cause the object to accelerate in the direction of the resultant force.

In other words, a resultant force on a body will cause it to change its velocity. This simply means that unbalanced forces will cause:

acceleration

deceleration

change in direction

Answer:18/2

Explanation:

its half

Answer:

1)

Acceleration (a)=change in velocity/ change in time

Velocity (v)=90m/s

Time=0.0005s

a=90/0.0005

The acceleration =180000m/s^2 or 180km/s^2

Force = mass x acceleration

m=40g= 0.04kg

F= 0.04x 180000

F= 7200N or 7.2kN

Answer:

1000J

Explanation:

Given parameters:

Mass  = 20kg

Speed  = 10m/s

Unknown:

Kinetic energy  = ?

Solution:

To solve this problem, we use the kinetic energy equation:

  Kinetic energy  = [tex]\frac{1}{2}[/tex] m v²  

m is the mass

v is the speed

 Now insert the parameters and solve;

     K.E  =  [tex]\frac{1}{2}[/tex]  x 20 x 10²   = 1000J

Answer: Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.

Answer:

A. As the blackbody radiator becomes warmer, it emits light of shorter wavelengths.

The temperature, and electromagnetic radiation has a relationship where blackbody radiator becomes warmer, it emits light of shorter wavelengths.

radiation can be regarded as the process of heat dissipation without contact with a body.

Therefore , temperature, and electromagnetic radiation of a black body works in the sense that

blackbody radiator becomes warmer during emissions.

Answer:

The Kinetic energy and mass are _directly_ proportional.

Explanation:

We know that Kinetic Energy is basically termed as the capacity of a body to do work.

Kinetic energy is often used to associate with moving objects, therefore, K.E is normally termed as the energy of motion.

The formula of K.E of an object of mass and velocity is defined

K.E = 1/2mv²

From the formula, it is clear that K.E is directly proportional to its mass and also directly proportional to the square of its velocity.

For example,

If A toy plane with a mass of 10 kg is flying at 20 m/s. Its K.E will be:

K.E = 1/2mv²

      = 1/2(10)(20)²

      = 1/2(10)(400)

       = 5(400)

      = 2000 J

Now, let suppose, if we double the mass of a toy plane i.e.

m = 20 kg

so

K.E = 1/2mv²

      = 1/2(20)(20)²

      = 1/2(20)(400)

      = 10(400)

      = 400 J

Therefore, the K.E is doubled when doubled the mass.

Therefore, the Kinetic energy and mass are _directly_ proportional.

just in internet tho

Signs look, listen, feel and smell for any signs of injury such as swelling, deformity, bleeding, discolouration or any unusual smells. When checking them you should always compare the injured side of the body with the uninjured side. Are they able to perform normal functions such as standing or moving their limbs

Secondary assessments are used in order to determine the injury, how the injury occurred, how severe the injury is, and to eliminate further injury.

Glad to help!

Answer:

Force = -4N

Explanation:

Given the following data;

Mass = 1kg

Initial Velocity = 20m/s

Distance = 50m

To find the acceleration;

We would use the third equation of motion;

Since, it comes to rest, its final velocity is zero (0).

V² = U² + 2as

Substituting into the equation, we have;

0 = 20² + 2*a*50

-400 = 100a

a = -400/100

a = -4m/s²

Now to find the force exerted

Force = mass* acceleration

Force = 1*(-4)

Force = -4N

Answer:

This is true

Explanation:

This is true because in other To measure the potential difference that is across a circuit, we have to place the device called the voltmeter to be in parallel withe the circuit, so as to get a measurement of the difference in energy from one side of the circuit to the other side. We can also refer to the Potential difference as the voltage and it is measured in volts using a voltmeter

Answer:

temperature

Explanation:

The movement of particles in an object is directly proportional to the temperature of the object. As the temperature increases, the kinetic energy increases too. This makes the last option (potential energy) incorrect.

The increased kinetic energy results to particles moving farther from each other, which means the particle attraction becomes weaker. This makes the third option (particle attraction) incorrect.

The particle arrangement shows the particles being widely separated. Therefore the arrangement decreases because they become less intact. This makes the first option (particle arrangement) incorrect.
