A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110.0 m.
Determine the acceleration of the car.
Answer: a = 8.10 m/s^2
Explanation:
The car starts at rest, so:
V0= 0m/s
t= 5.21m/s
S = 110.0 m
Using one of the five uniformly accelerated motion formulas
S= V0t + 1/2 at^2
but V0 = 0 m/s
S = 1/2 at^2
a= 2S/ t^2
a = 2(110m)/ (5.21 s)^2
a = 8.10 m/s^2

1) [30 points] find the rotation matrix after a clockwise rotation of 240 o about an axis that describes equal angles with respect to the original coordinate axes. 2) [30 points] at a given time two point charges q1
Since, ABCDEF is a regular hexagon,
The measure of the central angle of a regular polygon = [tex]\frac{360}{n}[/tex]
where n = number of sides of the polygon
The measure of the central angle of a regular hexagon =[tex]\frac{360}{6}[/tex] = 60°
That means when we rotate a regular hexagon by an angle in the multiple of 60°, the hexagon overlaps itself.
Therefore, by the rotation of 240° clockwise, point C will replace the position of point A.
The image of hexagon ABCDEF will become CDEFAB.
A rotation matrix is a transformation matrix in linear algebra that is used to make a rotation in Euclidean space. Rotation matrices depict rotations about the origin since matrix multiplication has no effect on the zero vector (the coordinates of the origin). Rotation matrices provide an algebraic description of such rotations and are widely utilized in geometry, physics, and computer graphics computations. In some publications, the term rotation is broadened to cover improper rotations, which are defined by orthogonal matrices with determinants of 1 (rather than +1). These incorporate appropriate rotations and reflections (which invert orientation). In other circumstances, where reflections are not taken into account, the label proper may be omitted.

After looking at sound waves in this way, why do you think people prefer to view sound waves transverse waves rather than
longitudinal?
If a wave is longitudinal that means that it is travelling in the exact same direction, at the exact same angle as the medium in which it is propagating. You can think of it like a stretched out slinky. If you push the slinky forward a little and then pull it back to its original position, a wave travels in the direction of the slinky's coils. Sound waves are just like that but the medium is all the particles that constitute air.

Answer:when a certain amount of violet light and yellow light shine on a metal surface only violet light produces an electric current describe how an increase in the intensity of each type of light will affect the amount of current produced, how does quantization help to explain these observations? Question thumb_up 100%
Explanation:
An increase in the intensity of violet light will lead to a proportional increase in the amount of electric current produced, as more violet photons will have enough energy to liberate electrons through the photoelectric effect.
However, an increase in the intensity of yellow light will not affect the electric current, as even with higher intensity, yellow photons do not possess sufficient energy to release electrons from the metal surface. This observation can be explained by quantization, which states that light energy is quantized into discrete packets called photons.
Each photon must possess a minimum energy threshold (the work function) to cause electron emission. Violet light photons have higher energy and can overcome the work function, while yellow light photons do not have enough energy and thus cannot produce a current, regardless of their intensity.

suppose a boat moves at 16.4 m/s relative to the water. if the boat is in a river with the current directed east at 2.30 m/s, what is the boat's speed relative to the ground when it is heading east, with the current, and west, against the current? (enter your answers in m/s.)
The boat's speed relative to the ground when it is heading east with the current is 18.7 m/s and west against the current is -14.1 m/s.
In the first case,
The velocity of the boat concerning water= 16.4 m/s
The velocity of the water concerning ground= 2.3 m/s
By using the formula of relative velocity:
V(b, g)= V(b, w) + V(w, g)
V(b, g)= 16.4i + 2.3i m/s
V(b, g)= 18.7i m/s
Hence, the magnitude of the velocity of the boat concerning the ground is 18.7 m/s along the current.
In the second case,
The velocity of the boat concerning water is -16.4 m/s
The velocity of the water concerning the ground is 2.3 m/s
By using the formula for relative velocity:
V(b, g)= V(b, w) + V(w, g)
V(b, g)= -16.4i + 2.3i
V(b, g)= -14.1i m/s
Hence, the magnitude of the velocity of the boat concerning the ground is -14.1 m/s against the current.

To derive components are displacement(s), velocity, time(t), and acceleration(a). :
The 1st equation of motion is : v = u + at
The 2nd equation of motion is : S = ut + (1/2)at²
The 3rd equation of motion is : v² = u² + 2 g S
Given, the initial velocity of an object u = v₀ in an upward direction so it will be negative, u = - v₀
The displacement of an object is the height of the object from the ground S = H and It is downward so it will be positive.
The acceleration = g as the object moving towards the ground ( positive in downwards ). The final velocity of the object is V before it hits the ground.
Using the 3rd equation of motion to find the velocity of the object,

What is speed ?speed is the rate at where someone or something moves is able to operate.
Let us convert cm to m for distance
C = 2.998× 10^8 ms
The relationship between distance, speed, and time is
T =1 ×10^6/8
Because in this case you are being asked how long or time it takes, make it the subject.
Rounding the quotient produces.
Adjust it again to fit the scientific notation.
The result is -
d= c×t
d=2.998×10^8 m/s 10^6 m/s
d=2.998
As a mathematical expression, the time taken for light is 2.998

With the aid pf sketch explain uniform speed and uniform velocity
If a body covers equal distances in equal intervals of time it has uniform speed. If a body covers equal displacement in equal intervals of time it has uniform velocity.
Speed is the rate of change of an object's position with respect to time in any direction. An object will have uniform speed, if the speed of the object remains constant and not varying.
Velocity is the rate of change of an object's position with respect to time in a particular direction. Uniform velocity is a condition in which a body covers equal displacements in equal intervals of time.
Therefore, if a body covers equal distances in equal intervals of time it is said to have uniform speed and if it covers equal displacement in equal intervals of time it is said to have uniform velocity.

Physics Suppose that, while in a squatting position, you stand on your hands, and then you pull up on your feet with a great deal of force. You are applying a large force to the bottoms of your feet, but no matter how strong you are, you will never be able to lift yourself off the ground. Use your understanding of force and motion to explain why this is not possible.
