Newton's 2nd law of motion is greater the mass of an object the more force it will take to accelerate the object

According to Newton’s second law of motion, weight depends on an object’s mass and the net force acting on the object. The given statement is true.

Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

The following equation help to understand the statement;

Force is defined as the product of mass and acceleration. Its unit is Newton.

F=ma

F=mg

Answer:

13 m in the + x direction.

Explanation:

Givens

m1 = m

m2 = 3m

v1= ? = x

v2 = - 3 m/s

v3 = v4 = - 1 m/s

Equation

Let x be the speed of the lighter object before collision.

Momentum before collision = momentum after collision

Solution

mx   - 3m * 3m/s = (m1 + m2)*(-1)

m(x - 3*3m/s) = (m + 3m)(-1)

m(x - 9) = - 4m                                      Cancel the ms

x - 9 = 4                                                 Add 9 to both sides

x = 9 + 4

x = 13 m/s

Crest describes the high point of a transverse wave. Therefore, the correct option is option A.

Transverse waves are those which oscillate in directions that are opposite to the wave's forward motion. Electromagnetic radiation, seismic waves, or water surface ripples are all examples of transverse waves.

A simple transverse wave can be represented by a sine or cosine curve because any point's amplitude—that are, its distance from the axis—is proportional to the sine (or cosine) associated with that angle. Crest describes the high point of a transverse wave.

Therefore, the correct option is option A.

Explanation:

A P E X

The energy of an electromagnetic wave that has a frequency of 5.0 * 10^5 Hz is 3.3 * 10 ^ -28 J

Electromagnetic waves are the waves that are created as a result of vibration between an electric field and  a magnetic field . They are composed of oscillating magnetic and electric field

Energy of Electromagnetic waves can be calculated by

Energy = h * f             where  h = plank's constant = 6.626 * 10^-34 J s.

                                                f = frequency of electromagnetic waves  

given :  h =  6.626 * 10^-34 J s.

            frequency =  5.0 * 10^5 Hz  

Energy  of  electromagnetic waves = (6.626 * 10^-34 J s)  *( 5.0 * 10^5 Hz)

                        = 33.13 * 10 ^ -29 J

Answer:

a = 6.25 m/s/s

d = 50 m

Explanation:

Given:

v1 (initial velocity)= 0 m/s (cz its at rest)

v2 (final velocity)= 25 m/s

t = 4s

a = ?

d = ?

to determine  acceleration

a = (v2 - v1)/ t

= (25m/s - 0m/s)/4s

= 6.25 m/s/s

to determine distance traveled

d = 1/2(v1 + v2)t

=1/2(0m/s+25m/s)(4s)

=50 m

Answer:

Answer in explanation.

Explanation:

Using Equation

[tex]v = u + at[/tex]

where v is the final velocity

u is initial velocity

a is acceleration

t is time taken

given u = 0, v = 25, t = 4,

[tex]25 = 0 + 4a \\ 4a = 25 \\ a = 6.25 \frac{m}{ {s}^{2} } [/tex]

Now, using equation

[tex]v {}^{2} = {u}^{2} + 2as[/tex]

where v and u remains the same, a = 6.25 and s is the distance,

[tex](25) {}^{2} = \: {0}^{2} + 2(6.25)s \\ 12.5s = 625 \\ s = \frac{625}{12.5} \\ s = 50m[/tex]

Answer: When an earthquake occurs energy is transferred, from where the rocks break, and travels throughout the world. The bigger the quake the further from the epicentre the waves will travel. There are four types of earthquake wave generated during an earth quake

Explanation:

The intensity of a natural disaster can be determined by the amount of energy transferred due to it.

Natural disasters include calamities with atmospheric, geological, and hydrological causes (such as droughts, earthquakes, floods, hurricanes, and landslides), which can result in fatalities, property damage, and social and environmental disturbance.

Here,

Internal and external forces work together to create natural disasters. The first is internal forces that are caused by the earth's internal heat energy and result in geologic hazards including earthquakes, volcanoes, and tsunamis.

Energy is transferred during an earthquake and propagates throughout the globe from the point at which the rocks split. The waves' distance from the epicenter increases with the size of the earthquake.

During an earthquake, four different kinds of seismic waves are produced. They transfer energy out of the earthquake's epicentre.

Hence,

The intensity of a natural disaster can be determined by the amount of energy transferred due to it.

We have that for the Question " constant applied force Fp of 11.0 N pushes a box with a mass=7 kg a distance x=15.0 m across a level floor. The coefficient of kinetic friction between the box and the floor is .110." it can be said that

the final velocity vf is

[tex]vf=3.83m/s[/tex]

and the applied force Fnew is

[tex]F_{new}=3.43N[/tex]

From the question we are told

A constant applied force Fp of 11.0 N pushes a box with a mass=7 kg a distance x=15.0 m across a level floor. The coefficient of kinetic friction between the box and the floor is .110. Assuming the box starts from the rest, what is the final velocity vf of the box at 15.0 m point? If there were no friction between the box and the floor, what applied force F new would give the box the same final velocity?

Generally the equation for the Force  is mathematically given as

F_p-\mu mg=ma

Therefore

11-0.110*7*9.8=7*a

a=0.49m/s^2

Using Newtons equation

v^2=u^2+2as

v^2=0+2*0.49*15

v=3.83m/s

Therefore

F=ma

F=0.49*7

F_{new}=3.43N

Therefore

the final velocity vf is

[tex]vf=3.83m/s[/tex]

and the applied force Fnew is

[tex]F_{new}=3.43N[/tex]

Answer:

A. The bus has more kinetic energy than the car.

Explanation:

As we know that

Kinetic energy is the amount of energy possessed by the body at the time when it is in motion.  

Also,

Kinetic energy = 1 ÷ 2mv²

Here m denotes the mass of the body

and v denotes the velocity of the body.

So it would be based on the mass & velocity of the body

As if the passenger bus contains more kinetic energy as compared to the car because of the big mass

Hence, the first option is correct
