Sled racing is simply a winter dog sport racing. Since Robb wants to win the next sled race, the advice that'll be given to him is that he should start at the top of the hill.
Other options such as starting at the bottom of the hill or the middle of the hill are wrong.
How can seismographs be used to predict hurricane intensity?
Answer: The earth is a noisy place. Seismometers, which measure ground movements to detect earthquakes, volcanic eruptions, and manmade explosives, are constantly recording smaller vibrations caused by ocean waves, rushing rivers, and industrial activity.

Since the maximum density can be found for a positive temperature, water's own weight will prevent it from freezing from the bottom up. However, the anomalous expansion of water has some negative consequences. ...

The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4o C to 0o C, and it becomes less dense. The density is maximum at 4 degree centigrade and decreases below that temperature as shown in graph#CarryOnLearning

I have always wondered if the saying it was hot enough to fry an egg on the sidewalk could 20 points be true. Please describe how you would determine if this could really happen. State any assumptions you would make. State any additional information that you would need and what you would do with the additional information
Answer:
This is one of the hottest summers America has ever seen and Jeremiah Warren is taking advantage of the heat wave and doing a little cooking…in his car!
It was about 98 or 99 degrees in Texas, so Jeremiah thought he’d head outside to see if it was hot enough to actually cook food. He buttered up a frying pan on his dashboard and filled it with an egg, cookie dough, a hot dog and bacon (mmm…bacon!). He set up another frying pan on the sidewalk and a few hours later he came back for a mid-day snack.

An ideal gas triples in volume in an adiabatic process. the initial pressure is 1.4 x 10^5 Pa. what is the final pressure? let y = 1.67.
5.8 x 10^4 Pa
2.2 x 10^4 Pa
1.4 x 10^4 Pa
1.0 x 10^5 Pa
Answer: 2.2x10^4
Explanation: in a adiabatic process pV^y = constant.
So V2=3V1 and p2 = p1 / 3^1.67 = 2.2x10^4 Pa
The Doppler Effect is caused by which of the following?
Select all that apply…
A - motion of the source
B - the type of wave
C - original frequency of the source
D - motion of the observer
E - type of medium the wave is in
Answer:
the type of wave
Explanation:
Description: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down.
What is the net force if you pull a cart to the right with 5N of
force and a friend pushes the left to the left with 5 N of force
Answer:
In this case the net force is zero.
According to Newton's third law of motion: For every action, there is an equal and opposite reaction. In this case the net force is zero.

Calculate the Kinetic energy of: 1. a rabbit weighing 10
kg moving at a speed of 5 m/s.
Answer:
125
Explanation:
use the formula e=1/2mv² and use m=10 and v=5
this produces the equation e=1/2x10x25=125
dont forget the units (J) ;)
Answer:
125J
Explanation:
K.e=1/2mv^2
=1/2(10)(5)^2
=125J

Differentiate the between, Heat, Thermal Energy, and Temperature.
Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat deals with the flow of thermal energy. Temperature is the physical manifestation of thermal energy, and deals with whether it feels cold or hot.
how do you know which magnitude is higher or how do you compare them?
Two moving objects have the same momentum. Object 1 has three times the mass of Object 2; therefore, Object 1 has:
the same the velocity of Object 2
three times the velocity of Object 2
nine times the velocity of Object 2
one-third the velocity of Object 2
one-ninth the velocity of Object 2
ANSWER
0ne third the velocity of object 2
Explanation:
P1=P2
m1v1=m2v2
v1=1/3.v2 [ since, m1=3.m2 ]
m2=m1/ 3
Answer:
one-third the velocity of Object 2

a 200 L of water tank is filled from a reason the inlet pipe at the bottom electrical overflow pipe prices with colourful the bottom boats 50 50 cm in diameter how much does the water rise in the overflow pipe in the water is heated from 10 degrees Celsius to 40 degrees Celsius
Answer:
The water rises by 4.45 m
Explanation:
Mass is constant
Mass = Volume /Specific Volume
Mass = 200/(1*10^-3*1.001) = 199.8 Kg
Volume after heating = specific volume * mass
= 1.008 *10^-3 lt/gm * 199800 gm
= 201.398 t
Change in volume = 1.3986
(pi)r^2 *h = 1.3986 *10^-3 m^3
3.14 * (1*10^-2 m)^2 *h = 1.3986 *10^-3 m^3
H = 4.45 m
Give 1 real life example of a scenario that takes advantage of the inverse relationship between force and time when impulse is constant. Describe how it is an example of impulse and how force and time are involved.
Answer:
On real life example of a scenario that takes advantage of the inverse relationship between force and time when impulse is constant is when making a serve with a lawn tennis racket
How It is an example of impulse is that when a serve is made by moving the bat slowly, the lawn tennis player uses less force and the ball is in contact with the string for longer a period
When however, the lawn tennis player moves the racket faster, with the strings of the racket highly tensioned he uses more force and the ball also spends less time on the racket to produce the same momentum
Explanation:
The impulse of a force, ΔP is given by the following formula;
ΔP = F × Δt
Where ΔP is constant, we have;
F ∝ 1/Δt
Therefore, for the same impulse, when the force is increased, the time of contact is decreases and vice versa.
