Answer:
Infinity
Explanation:
When you have a limit approaching infinity one method you can use is to remember that the highest power dominants all of the other ones so when we have (t^2)/t-1 like in your problem, we see that t^2 has the highest power of 2 so if that's going to infinity and it's not being divided by any powers higher than it will just be inifinity.
We have that for the Question, it can be said that in the limit calculations below, if you need to use -â or â, enter -infinity or infinity. the limit is
[tex]Lim_{t->\infty} p(t)= \infty[/tex]
From the question we are told
Tafu is working with subatomic particles in the physics lab. a positron is traveling in a straight line down the particle accelerator.tafu models its position with the function
p(t)= t2 t â 1 where t>1.
in the limit calculations below, if you need to use -â or â, enter -infinity or infinity.
(a) calculate the limit
Generally the equation for the Question is mathematically given as
[tex]p(t)=\frac{t^2}{t-1}\\\\Therefore\\\\For Lim_{\infty}\\\\We have\\\\ Lim_{t->\infty} p(t)= Lim_{t->\infty}\frac{t^2}{t-1}\\\\[/tex]
Since, the equivalent degree of numerator (t^2) is greater than that of the denominator
[tex]Lim_{t->\infty} p(t)= \infty[/tex]

What is the unit of a force, and what is 1 unit equivalent to?
Answer:
Newton
Explanation:
The unit of force is Newton and it is given after Sir Isaac Newton for his tremendous works in this regard.
Force is the product of mass and acceleration of a body.
Force = mass x acceleration
The unit of mass = kg
acceleration = m/s²
So;
1N = 1kgm/s²
Therefore, the unit of force is newtons and 1N is equal to 1kgm/s²
Earth's rotation causes winds to veer to the west or to the east. This is known as the Coriolis effect.
Lesson 1.06
Question 5 options:
True
False
Earth's rotation and spherical shape cause winds to veer to the right (in the northern Hemisphere) or to the left (in the southern Hemisphere) of the direction they want to go. This is known as the Coriolis effect.
If you didn't know that you're on a rotating Earth, and you looked at the patterns of the winds, you'd think there's some kind of force that's making the airflow veer to the right or left of the direction it actually wants to go. This is known as the Coriolis force. It's a"pseudo force", because it doesn't really exist. It only LOOKS like it's there, because of the Earth's rotation and spherical shape..
The statement "Earth's rotation causes winds to veer to the west or to the east" is true about the Coriolis effect.
What is the Coriolis effect?Fluid materials such as wind and ocean currents take different directions depending on the hemisphere, this movement of deviation is called the Coriolis effect.
Characteristics of the Coriolis effectThe Coriolis effect occurs when masses of air or water move along terrestrial meridians, and their trajectory and speed are modified by it.The winds or ocean currents that move along a meridian are diverted by accelerating in the direction of rotation (east) if they go towards the poles or the opposite (west) if they go towards the equator.Therefore, we can conclude that the force that tends to deflect the trajectory of objects moving across the entire earth's surface is known as the Coriolis effect.

visible light
Explanation:
Edge 2021
Infrared light is typically used to make images based on the temperatures of objects.
What is meant by electromagnetic spectrum?The range of all EM radiation arranged from high to low frequency (short to long wavelength) according to their frequency or wavelength. is known as the electromagnetic spectrum (EM).
Here,
Similar to visible light, X-rays are a type of electromagnetic radiation. X-rays have a higher energy than light, on the other hand, and can penetrate most materials, including the human body.
Images of inside body tissues and structures are produced using medical x-rays.
Electromagnetic energy in the infrared region of the spectrum can be seen by them. There is a relationship between an object's temperature and the electromagnetic radiation it releases since infrared radiation is strongly related to object temperature.
Hence,
Infrared light is typically used to make images based on the temperatures of objects.

Explanation:
A spring has a constant of 875 N/m. and the mass which will cause this spring to stretch 4.5 meters is 401.78 kg.
What is Spring constant?The spring constant is a characteristic of a spring which is defined as the ratio of the force affecting the spring to the displacement which is caused by that force. The SI unit of spring constant is N.m⁻¹ (Newton per meter).
The spring constant is:
F = -k/ x
where, k is the spring constant
F denotes the force,
and x denotes the change in the length of the spring.
k = 875N/m
x = 4.5m
We know that
Kx = mg
m= kx/ g
m = 875 × 4.5/ 9.8
m = 401.78kg
Therefore, the mass which will cause this spring to stretch 4.5 meters is 401.78 kg.

Which equation should be used to calculate the speed of a wave?
speed = frequency x wavelength
speed = frequency x hertz
speed = period x wavelength
speed = period x hertz
The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is the formula for wave speed?The speed of a wave is calculated by the equations: V = λ . f or V = λ/T, and the unit of measurement is m/s. This speed depends on the medium: in gaseous media, the speed is lower than in solid media.
See more about wave speed at brainly.com/question/10715783
The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is Speed of wave?Wave speed is the movement of a progressive wave, which is an energy-moving disturbance that takes the shape of an oscillation and moves from one place to another.
The wavelength and frequency of a wave both affect its speed. A wave's speed is a crucial factor because it enables us to estimate how quickly the wave will disperse in the medium, which is the substance or material that will carry it.
This is the water in the case of ocean waves and the air in the case of sound waves. The kind of wave and the physical properties of the medium in which it is flowing also affect a wave's velocity.
Therefore, The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

how much energy must be absorbed by water with a mass of 0.5kg in order to raise the tempature from 30c to 65c
Answer:
62760J
Explanation:
Given parameters:
Mass = 0.5kg = 500g
Initial temperature = 30°C
Final temperature = 65°C
Unknown:
How much energy is absorbed by the water = ?
Solution:
To solve this problem, we use the expression below:
H = m C Δt
H = m x C x (t₂ - t₁ )
m is the mass
C is the specific heat = 4.184J/g°C
t₂ is the final temperature
t₁ is the initial temperature
So;
H = 500 x 4.184 x (65 - 30) = 62760J

Answer:
11. A door accelerating when pushing it.
12. A person sliding along the floor.
13. Water dropping from the faucet.
14. Courtains descending when loosening them.
Explanation:
For kinetic energy, any example that does not move horizontally will do. Something accelerating or decelerating is a good example (Ek=1/2mv^2, where v is velocity).
For potential energy try to think of things moving vertically. Potential energy comes from the height of an object (Ep=mgh, where h is height).
Notice that example 13 and 14 represent potential energy turning into kinetic energy, height becomes lower, so velocity increases.
