Answer:

true

Reason for answer

it can't be false

Hey,

Following the second Newton's Law  :

✔ We apply : F = m x a ⇔ m = F/a with F in N, m in kg and a in m/s²

the object therefore has a mass of 8 kg

Answer:  343

Explanation:  i know it sounds weird but its right

The frequency for the maximum constructive interference will be 343 Hz.

The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.

The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.

From the constructive interference;

[tex]\rm L_1-L_2 = 2 \lambda \\\\ 2\lambda=8-6 \\\\ \lambda= 1 \ m[/tex]

The frequency is;

[tex]\rm f= \frac{c}{\lambda} \\\\ f= \frac{343}{1} \\\\ f= 343 \ Hz[/tex]

Hence,the frequency for the maximum constructive interference will be 343 Hz.

The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.

Since

Length L = 6.25 m

g = 9.8 m/s²

So,

T = 2π√(L/g)

T = 2π√(6.25 / 9.8)

T = 5.01 sec

Hence, The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.

Musicians use frequency is pitch.

The shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound. The shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound. Hope it helps!

Answer: The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if the distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

Answer: 63.43 m

Explanation:

Given

Car lands 68.38 m away from the base of the garage

Stuntman drove the car with speed [tex]u=19\ m/s[/tex]

Since there is no acceleration in the horizontal direction, so there is no change in velocity

[tex]\Rightarrow 68.38=19\times t\\\Rightarrow t=3.598\ s[/tex]

time taken to cover 68.38 m is 3.598 s

In this time car travels a vertical distance of h

Such that we can write

[tex]\Rightarrow h=u_vt+\frac{1}{2}at^2\\\\\Rightarrow h=\frac{1}{2}gt^2\\\\\Rightarrow h=0.5\times 9.8\times (3.598)^2=63.43\ m[/tex]

A coin falls off a table and is traveling to the ground. There is a net force on the coin which is responsible for the motion of the coin. Thus, the correct option is A.

The net force can be defined as is the sum of all the forces which are acting on an object. Net force acting upon an object can accelerate its mass. Some other forces also acts on a body either at rest or motion. The net force is used in a system when there is a significant number of forces acting on the object.

A coin which falls off a table and is still traveling to the ground. Then, it can be concluded that there is a net force which is acting on that coin which is responsible for the motion of the coin.

Therefore, the correct option is A.

Answer:

c. earth rotates on it tilted axis and orbit around the sun at the same time​

Explanation:

Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.

This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun. Thus, this makes us to experience day and night (sun rise and sun set) due to the rotation of planet about its axis.

Hence, the sun rise and set because the earth rotates on it tilted axis and orbit around the sun at the same time​

As par circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.

Pie charts are another name for circle graphs. The graph is shaped like a circle, with many wedges that each represent a portion of the overall.

The circle graph is commonly referred to as a pie chart since these wedges frequently resemble pie slices. The circle graph's angles are proportionate to the quantity they each represent.

According to circle graph:

Total number of student in the particular school = 2π radian.

So, one-fourth of total number of student in the particular school = 2π/4 radian

= π/2 radian.

Hence, according to circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.
