The period of a simple pendulum only depends on its length, and the acceleration of gravity in the place where the pendulum is swinging.
It's really tough to answer the question, because both of these things are in a fraction in the formula for the period . . . the length is the numerator, and the local acceleration of gravity is the denominator. So which one has a greater effect on the period really depends on what those numbers are before anything changes.

A sprinter reaches a velocity of 2 m/s in just 1 second. At a constant rate of acceleration, how long does it take for her to double this velocity? What is her acceleration during this time period? Show you work and explain your answer.
Answer:
See the answer below
Explanation:
Acceleration is the ratio of velocity and time. Hence;
Acceleration of the sprinter = 2/1 = 2 m/s2.
When the acceleration is constant and the velocity is double:
acceleration = velocity/time
2 = 4/time,
time = 4/2 = 2 s
Hence, the time it will take for the velocity to double with constant acceleration is 2 s. The sprinter's acceleration during this period would be 2 m/s2.
Acceleration is the change in velocity with time. Hence, the time taken to double velocity is 2 seconds and the constant value of acceleration is 2m/s²
Acceleration is the change in velocity with time ;
Acceleration = (△velocity) ÷ time Velocity = 2m/s ; time = 1 secondAcceleration = (2 ÷ 1) = 2m/s²
Double the value of velocity = 2(2m/s) = 4m/s
At constant acceleration ; Acceleration = 2m/s²
Inputting the Values into the equation :
2 = 4 / time
(2 × time) = 4
Time = 4/2
Time = 2 seconds
Therefore, the time taken to double the velocity is 2 seconds

An object, initially traveling at a velocity of 52 m/s, experiences an acceleration of -9.8 m/s². How much time will it take it to come to rest? *
Answer:
5.3 s
Explanation:
Given:
v₀ = 52 m/s
v = 0 m/s
a = -9.8 m/s²
Find: t
v = at + v₀
0 m/s = (-9.8 m/s²) t + 52 m/s
t = 5.3 s
A gas is currently at a temperature of 84º C at a volume of 10 liters. If the pressure is kept the same and the temperature is lowered to 72º C, what will the new volume be?
Answer:
9.66 L
Explanation:
The following data were obtained from the question:
Initial temperature (T1) = 84 ºC
Initial volume (V1) = 10 L
Final temperature (T2) = 72 ºC
Final volume (V2) =..?
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
Initial temperature (T1) = 84 ºC
Initial temperature (T1) = 84 ºC + 273 = 357 K
Final temperature (T2) = 72 ºC
Final temperature (T2) = 72 ºC + 273 = 345 K
Since the pressure is constant, it means the gas is obeying Charles' law. Thus, we shall determine the new volume of the gas as follow:
Initial temperature (T1) = 357 K
Initial volume (V1) = 10 L
Final temperature (T2) = 345 K
Final volume (V2) =..?
V1/T1 = V2/T2
10/357 = V2/345
Cross multiply
357 × V2 = 10 × 345
Divide both side by 357
V2 = (10 × 345) / 357
V2 = 9.66 L
Thus, the new volume of the gas is 9.66 L.

Darth Vader uses his powers to accelerate a 650.00 kg spaceship from rest to 100.00 m/s in 7.0 s. What is the net force on the spaceship?
Answer:
This Means Nothing to ME
Explanation:
I HAVE A tradition of doing a little analysis on one of my favorite movie franchises to celebrate Star Wars Day (May the Fourth Be With You). Given that Rogue One: A Star Wars Story recently appeared on DVD and various streaming services, I think its OK to look at that film without worrying about spoilers. In this case, I will calculate Darth Vader's power output as he uses the Force.
To calculate the power needed to lift this poor fellow, I can estimate how high Vader lifts him and at what speed. If I guess that the rebel is 1.75 meters tall (the average height of a man here on Earth, so I'll assume the same holds true on whatever planet the rebel calls home) then I can get an approximate scale for the scene. With that, I can use video analysis to plot the vertical position of the rebel as a function of time

Convert km to cm;
Solution:
100cm = 1m
1000m = 1km
So,
100,000cm = 1km
1km = 100,000cm
0.95km = 0.95 x 100000 = 95000cm
A skyjumper freely falls for 7 s. What is her final speed then?
Answer:
if we ignore air resistance .. which might slow her down a lot towards the end of the 7 seconds.. but we will just ignore that for this question
Explanation:
then V=Vo+a*t
Vo=0
V=a*t
V=9.8(7)
V=68.6 m/s just a little over 150 MPH.. but.. I think terminal velocity is close to 120... soo hmm maybe about that fast... but that with air resistance.. so this problem depends a lot on if you're going to ignore that
How are forensic anthropologists and archaeologists different? A. Forensic anthropologists study bodies, and archaeologists search for artifacts. B. Forensic anthropologists study bodies, and archaeologists only study buildings. C. Forensic anthropologists study artifacts, and archaeologists study bodies. D. Forensic anthropologists study buildings, and archaeologists study bodies.
Answer:
A
Explanation:
Forensic anthropology is a branch of anthropology that analyzes the remains of a body in order to solve criminal cases. A forensic anthropologist, therefore, is a scientist that studies and analyzes remains of bodies in order to unravel criminal cases.
Archaeology, on the other hand, has to do with the analyses of artifacts in relation to human culture. An archaeologist is a person that studies artifacts mainly.
Hence, while a forensic anthropologist specializes in the study of bodies, archaeologist searches and studies artifacts.

PLeasseee help me!!
Answer:
Molecule
Explanation:
A molecule is the smallest particle of sugar (glucose - C6H12O6) or any other substance because a molecule possess all properties of that particular substance.
Molecules are responsible for all the chemical and physical properties of a substance, so molecules decided the properties of sugar as well. If the molecule will be broken, it will lose its properties. Sugar is composed of molecules that include 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen.
Hence, the correct answer is "Molecule".

A car traveled 3000 m at a constant speed of 20 m/s. How long did it take to travel this distance?
Answer:
t = 150 [s]
Explanation:
To solve this problem we must take into account that the car travels at a constant speed, that is, there is no acceleration or it is equal to zero, therefore we can use the following equation of kinematics.
X = Xo + (v*t)
where:
x = final point [m]
Xo = initial point [m]
v = constant velocity = 20 [m/s]
t = time [s]
X - Xo = the distance traveled = 3000 [m]
3000 = 20*t
t = 150 [s]

Give three reasons why it’s important to give children opportunities to pretend play or have make-believe situations
Answer:
The first reason for children to have pretend play is that it allows the child to learn how to interact socially. The child is able to take turns, share responsibility, develop how people feel and react the situation. Another reason is that it helps the child develop their critical thinking skills. They may have to creatively solve a problem, or think what they may need in real life for the pretend play. It increases the child's ability to think through those types of situations. The final reason it is important for a child to have pretend play is that it helps develop their language skills. If the child is imitating a dad, mom, teacher, etc. they will attempt to use the same language that person uses. This helps the child connect new language abilities and skills.
Explanation:
Answer:
The top 3 reasons for encouraging children to pretend play and make-believe include:
1. To encourage imagination and creativity.
2. To support social and emotional development.
3. To improve language and communication skills.
LeBron James runs 260 meters East, then realized he dropped is basketball. He turns around and walks 54 meters West until he finds his ball. It takes him 45 seconds for the full trip. How far away is he from where he started?
Answer:
206 meters East
Explanation:
Assuming that the starting point of Lebron James 0. He ran from point 0 to 260 meters in the Eastern direction. His displacement is now 260 meters to the East.
He then turned from the Eastern to the Western direction - opposing directions - and then walked 54 meters to find his ball. His displacement from the starting point will now be:
260 - 54 = 206 meters in the Eastern direction.
