Initial velocity exists at 19.6 m per second. Plus acceleration exists equivalent to expression due to gravity, but it exists downward, so it will be negative -9.8 m per second squared and time exists three seconds, so this exists equivalent to this gives us - 9.8 meter per second velocity after 3 seconds.

The acceleration of the ball will be a constant [tex]$9.8 \frac{\mathrm{m}}{\mathrm{s}^2}$[/tex] (downward), regardless of whether the ball exists traveling upward or downward.

The equation that makes this calculation simplest is

[tex]$$V_f=V_i-g(\Delta t)$$[/tex]

where the negative sign has been used to account for the opposite directions of [tex]$V_i$[/tex] and g. After 3 seconds,

[tex]$V_f=19.6-(9.8)(3)=19.6-29.4=-9.8 \frac{m}{s}$$[/tex]

The negative result tells us that the ball is on its way downward by this time (consistent with our choice of a negative value for the downward acceleration of gravity).

A shorter period implies a higher frequency because the relationship between the period and frequency is inverse.

T= 1/f = 1 / 1×10⁸s = 10ns

An event's repetitions per unit of time are what determine its frequency. It is also referred to as ordinary frequency in comparison to angular frequency and sometimes as temporal frequency in contrast to spatial frequency. Period, the inverse of frequency, is the duration of time required for one cycle of a repeating event. For instance, a heart that beats at a rate of 120 beats per minute (2 hertz) has a period (T) of 0.5 seconds between each beat (60 seconds divided by 120 beats).

A frame of reference is just a set of coordinates that are used in the study of physics to calculate things like position and velocity. Axes that specify the three dimensions of space within the frame of reference are often included in such a frame.

A railway platform is an illustration of an inertial frame of reference. The platform doesn't move, hence it satisfies the requirement for not accelerating. The platform's objects move according to the law of inertia.

An acceleration with respect to an inertial frame characterizes a non-inertial reference frame. In general, an accelerometer at rest in a non-inertial frame will pick up a non-zero acceleration. While all inertial frames share the same laws of motion, non-inertial frames have different laws of motion depending on the acceleration. For example, let's imagine you are driving through a stop signal in an automobile. The automobile has stopped moving. The automobile accelerates when the light turns green. The car is not an inertial frame of reference when it is accelerating. You will feel yourself "pushed" into the seat if the acceleration is significant enough.

Spring is an elastic object that holds mechanical energy. Typically, springs are fabricated from spring steel. Springtime has many different patterns. A conventional spring without stiffness variability features exerts an opposing force that is roughly proportional to its change in length when it is compressed or stretched from its resting state. The word is frequently used to describe coil springs in daily speech (this approximation breaks down for larger deflections). The rate also referred to as the spring constant, is the proportion of a spring's change in force to change in deflection. In other words, it is the force against the deflection curve's gradient.

Convert the angle to radian

180⁰ = π

Hence, the total angle should be

A + B + C = π

π/9 + 3π/8 + C = π

Answer:

i. Point A

ii. None

iii. All points

iv. F

v. None

vi. All

vii. None

Explanation:

i. Not quite sure if I'm interpreting the diagram right, but from the second the ball is released, it will start accelerating. Point A is where the velocity will be closest to 0 but not necessarily 0 as it will have started accelerating downwards.

ii. Assuming standard directions for vectors, the velocity is positive at none of the points as the ball is travelling in a downwards direction.

iii. Since the ball is always travelling downwards, its direction and therefore velocity is a negative number at all points in this diagram.

iv. The ball is accelerating as it falls so the further or the longer it falls, the faster its velocity, therefore in this diagram, it is fastest at point F.

v and vi. Assuming same direction principles as ii and iii (as acceleration and velocity are both vectors), acceleration is always downwards, therefore it is positive at no points, and negative at all of them.

vii. Acceleration due to gravity is always constant, so unless the ball is not moving (being held by the boy), acceleration is not 0 at any of the points.

Based on Einstein's theory of gravity, if the sun and its mass were to suddenly disappear, earth would stay in its current orbit for a few minutes before taking off into space.

The Earth would be drawn to a new center of gravity if the sun disappeared. Earth's gravity would change, as would that of the rest of the solar system, and Earth would begin to drift into space since there would no longer be a steady source of energy from the sun. It is a foolish dream to think that life could exist without the sun forever. Humans could be able to survive for a while in some sort of base, such as a nuclear-powered dome.

The good news is that there wouldn't be many living things for the radioactive waste to endanger; however, there also probably wouldn't be any liquid water to cool the power system. All photosynthetic species, including plants and algae, would die if just the sun's light persisted.

As from the given data, the clock in a spaceship is observed to run at a speed of 3/5 of a similar clock that rest on the earth is

T/T° = 3/5

When time moves at a high rate of pace, it slows down. The quantity of time dilation increases as an object moves more quickly. The constant speed of light, independent of the source of the light and the viewpoint of the observer, is partially explained by time dilation.

The expression for the time dilation is given by

T = γT°

γ = T/T°

γ = 1/√1 - v^2/c^2 is time dilation

Substituting the values in the above equation as,
