3. An object accelerates from rest, with a constant acceleration of 4.5 m/s, what will its
velocity be after 30 s?
An object accelerates from the rest, which means that the initial speed of the object is 0 m/s, so the final velocity after 30 seconds will be equal to 135 m/s.
What is acceleration?Acceleration refers to the rate of change in both speed and direction of velocity over time. When something moves slower or faster in a straight line, it is said to have been accelerated. So because direction is always shifting, motion on a circular accelerates even while the speed is constant. Both factors add to the acceleration for every other types of motion.
It is a vector quantity, since acceleration has a magnitude and a direction. Another vector quantity is velocity. The velocity vector change during a certain period of time, split by that period of time, is the concept of acceleration.
The given information in the question is,
Initial speed, u = 0 m/s
Time, t = 30 s
Acceleration, a = 4.5 m/s²
Use the equation of motion,
v = u + at
v = 0 + (4.5)(30)
v = 135 m/s
Therefore, the final velocity of the object will be 135 m/s.

Silver is a white metal that is an excellent conductor. Silver tarnishes when exposed to air and light. The density of silver is 10.49 g/cm3. The melting point is 962oC and the boiling point is 2000oC. A chemical property of silver is A) density. B) melting point. C) tarnishes in air. D) that it is a conductor.
Answer:
C) tarnishes in air.
Explanation:
Silver is a white metal that tarnishes when it is exposed to air that has the presence of sulphur gases. When exposed, it begins to undergo discoloration. It starts to darken as a result of the reaction with the gases causing the silver object to be disfigured. The commonest sulphur containing gas is hydrogen sulfide. As relative humidity goes up, silver can also tarnish faster.

How is ice more reflective than water?
Answer:
In fact, ice is slightly less reflective than water. The reflectivity is related to the refractive index (in a rather complicated way) and the refractive index of ice is 1.31 while the refractive index of water is 1.33. The slightly lower refractive index of ice will cause a slightly lower reflectivity. In both cases, the reflectivity is about 0.05 i.e. at an air/water or air/ice surface about 5% of the light is reflected.
Explanation:
Answer:
In fact ice is slightly less reflective than water. ... The net result is that much more of the light is reflected from snow. So the difference isn't anything fundamental, it's just because water is continuous while snow isn't.

A body moving with uniform acceleration has a velocity of 15.9 cm/s when its x coordinate is 4.26 cm.
If its x coordinate 2.62 s later is −3.18 cm, what is the x-component of its acceleration?
Answer in units of cm/s²
Answer:
[tex]a=-14.3\ cm/s^2[/tex]
Explanation:
Given that,
Initial velocity of a body, u = 15.9 m/s
Initial position, [tex]x_i=4.26\ cm=0.0426\ m[/tex]
Final position, [tex]x_f=-3.18\ cm=-0.0318\ m[/tex]
Time, t = 2.62 s
We need to find the x-component of its acceleration. using second equation of motion to find it as follows :
[tex]x_f-x_i=ut+\dfrac{1}{2}at^2[/tex]
Putting all the values to find a.
[tex]-3.18-4.26=15.9(2.62)+\dfrac{1}{2}a(2.62)^2\\\\-49.098=3.4322a\\\\a=-14.3\ cm/s^2[/tex]
So, the acceleration of a body is [tex]-14.3\ cm/s^2[/tex].

URGENT! Why are vectors important to the concept of relative velocity?
Answer:
Explanation:
In physics, vectors are useful because they can visually represent position, displacement, velocity and acceleration. When drawing vectors, you often do not have enough space to draw them to the scale they are representing, so it is important to denote somewhere what scale they are being drawn at.

So, the acceleration due to gravity on the asteroid is [tex]3.33\times 10^{-9}\ m/s^2[/tex].
You're taking your first dive in ALVIN (Fig 10.13) to witness a hot spot on the ocean floor. As you descend and arrive on site, what are your first impressions?
Answer:
Explanation:
The experience is magnanimous and wonderful when witnessing the hotspot site. It was a great feeling! I could witness the red hot lava oozing out to the ocean floor from the subsurface like water from a hot-spring, and immediately, a cooling effect occurs. At that current time, the gas was coming up in the form of gas bubbles. I believed there was a mini-volcano located inside the ocean! The scene was fascinating, just like inserting a red-hot metallic-iron ball into the cool water, thereby creating a fizzing of gas and the ball's immediate cooling. It was a remarkable experience of witnessing an underwater volcano with the erupting lava and its immediate cooling to form a solid material.

A stone is projected vertically upwards with a velocity of 12ms'. Calculate or find:
a) How long it took the stone to reach its maximum height.
b) Maximum height reached by the stone.
Answer:
The acceleration of the stone will be -9.8 m/s^2, because of the acceleration of earth's gravity, the initial velocity will be 12 m/s, and the final velocity will be 0 m/s. Therefore, we can solve using a kinematic equation to solve the problems:
a)
Final Velocity = Initial Velocity + Acceleration * Time
0 = 12 + -9.8*t
-12 = -9.8*t
t = 12/9.8 ≈ 1.224
Therefore, the time is equal to 12/9.8 ≈ 1.2245 seconds.
b)
Displacement = (Initial Velocity + Final Velocity)/2 * Time
d = (12+0)/2*1.2245
d = 6*1.2245
d = 7.347
Therefore, the maximum height is approximately equal to 7.347 meters.

A hockey puck slides across the ice at a constant speed.
Which of the following is true?
1. It is in equilibrium.
2. The puck is at rest.
3. The puck is moving and thus not in equilibrium.
4. None of these
5. The puck can be considered neither at
rest nor in equilibrium.
As a hockey puck slides across the ice at a constant speed, it is n equilibrium. The correct option is 1.
What is equilibrium?Chemical equilibrium is the condition in which both the products and reactants are prevalent in concentrations that have no further tendency to change with time, resulting in no observable change in the system's properties.
When a reaction and its reverse reaction proceed at the same rate, this is referred to as chemical equilibrium.
Both forward and reverse reactions occur as a system approaches equilibrium. The forward and reverse reactions are proceeding at the same rate in equilibrium.
It is in equilibrium because it achieves dynamic equilibrium by moving in a straight line at constant speed. The net forces are equal to zero.
Thus, the correct option is 1.

A student in Europe performs the same experiment, but the AC frequency there is 50 Hz. How different length of sensitized tape will he need in order to get 25 spark marks, compared to the length of your tape for the same number of marks? Give the result in centimeters.
Answer and Explanation:
The computation is shown below:
The ac frequency in the United States is 60 Hz
The ac frequency in Europe is 50 Hz
So,
Time for 25 spark in United stated is 25 ÷ 60 s
Time for 25 spark in Europe is 25 ÷ 50 s
Now
Tape length in United States is
= 0.5 × 9.8 × (25 ÷ 60)^2
= 0.85 m
= 85 cm
And,
Tape length in europe is
= 0.5 × 9.8 × (25 ÷ 50)^2
= 1.225 m
= 122.5 cm
So, As it can be seen that
= 122.5 cm - 85 cm
= 37.5 cm
Europe has 37.5 cm more than in the United States
