This frequency definition leads us to the simplest frequency formula: f = 1 / T . f denotes frequency and T stands for the time it takes to complete one wave cycle measured in seconds. The SI frequency unit is Hertz (Hz), which equals 1/s (one cycle per second)

Speed and velocity use the same formula for calculations. However, an object can have a different average speed and average velocity because of
displacement
True
False
Answer:
true..........................
Speed and velocity use the same formula for calculations. However, an object can have a different average speed and average velocity because of displacement. This is true statement.
What are velocity and speed?As a vector quantity with both magnitude and direction, velocity has both. This term refers to the speed at which an object is moving or shifting positions.
Since speed is a scalar quantity, it lacks direction. It indicates the rate of a moving thing. When a particle's speed is high, it indicates that it is travelling quickly, and when it is low, it indicates that it is going slowly.
The displacement of a body during a period of time divided by the passage of time yields the average velocity of the body during that period.
The distance travelled by a body in a given amount of time, divided by the amount of time, is the body's average speed.

How old is the sun and since its birth, how has the sun changed?
During its lifespan, what characteristics of the sun will change?
Answer:
(3rd Question about the Black Widow Pulsar)
J1311 is a fast spinning neutron star, which means it emits strong beams of radiation from it's poles.
As the beam of the pulsar sweeps across the surface of the companion star, it heats it up and blows its material outward into space, thus decreasing its mass.

Projectiles do not follow a predictable path.
Please select the best answer from the choices provided
A
B
C
D
Answer:
Your answer should be B. a parabola.
Explanation:
The path of the projectile in the absence of friction is a parabola. Therefore, option (b) is correct.
What is the projectile motion?Projectile motion can be described as a form of motion experienced by a projectile that is projected near the surface of the earth and moves along a curved path under the action of gravity. This curved path is to be a parabola, but may also be a straight line in special cases when the projectile is thrown directly upwards.
The study of such motions is known as ballistics and the only force that is actively exerted is gravity, which acts downward, thus giving the object a downward acceleration toward the Earth’s center of mass.
No external force is required to maintain the horizontal velocity component of the object's motion because of the object's inertia. Other forces, such as aerodynamic drag or internal propulsion need additional analysis.
Therefore, the path of an object or projectile is generally parabola in the absence of friction.

A 55 kg skier is at the top of a slope. The vertical distance between start and finish is 10m. (a) What is her Potential Energy? (b) How fast is she moving at the bottom of the hill?
Explanation:
Given that,
Mass of a skier, m = 55 kg
The vertical distance between start and finish is 10 m.
(a) The potential energy of a skier is given by :
[tex]E=mgh\\\\E=55\times 9.8\times 10\\\\=5390\ J[/tex]
(b) When she reaches the bottom of the hill, the potential energy is converted to kinetic energy. So,
[tex]5390=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2\times 5390}{55}} \\\\v=14\ m/s[/tex]
Hence, her potential energy is 5390 J and at the bottom of the hill she is moving with a speed of 14 m/s.

A skateboarder rolls down the sidewalk with an initial velocity of 0 m/s. If her acceleration is
1.5 m/s”, how long will it take her to reach the bottom 120m away?
Answer:
80m/s
Explanation:
to find it you have to work it out by using the formula distance divided by speed to find time.
The time taken by the skateboarder to reach the bottom 120m away is 80 sec.
What is Acceleration?Acceleration may be defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities as it has both magnitude and direction.
When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing. If an object is speeding up and moving in a positive direction, it has a positive acceleration.
According to the question,
Speed of the skateboarder = 1.5 m/s
The total distance needs to be traveled = 120m
Total time taken =?
The Formula for calculating time is as follows:
Speed = Distance/time. Time = Distance/speed = 120/1.5 = 80 seconds.Therefore, the time taken by the skateboarder to reach the bottom 120m away is 80 sec.
