A baseball diamond is a square (don’t be fooled that it is usually shown rotated by 45°). Each side of the square is 90 feet long (to two significant figures). How far must a fielder throw the ball from second base to home plate?
A line from second to home creates a right triangle with 45 degree angles.
This makes the diagonal line the side length of the square multiplied by the sqrt(2)
Second to home = 90sqrt(2) = 127.279 feet ( round answer as needed)

In a parachute, falling steadily at 7.5m/s, how long does it take to reach the ground from 3,000 m high?
Answer:
25 minutes
Explanation:
specific heat capicity of water is 4200Jkg-1 C-1 . what its meaning .
The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C. Lead will warm up and cool down faster because it doesn't take much energy to change its temperature.

During which portion of its motion-A, B, or C- does the train have the smallest speed?
Answer:
1
Explanation:
B is -1 m/s but it transfers to 1
During portion B of its motion, the train would have the smallest speed because the slope of the position time graph is the lowest for portion B.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.
As given in the problem we have to find out for which portion of the motion the train would have the smallest speed,
As we know that speed is given by the slope of the position-time graph.
For portion C the slope of the given position-time graph is highest therefore the speed of the train would be largest for portion C.
For portion B the slope of the given position-time graph is lowest therefore the speed of the train would be lowest for portion B.

What are some examples of relative motion?
Relative Motion refers to the motion or speed of any object in respect to a particular point. For example, a ball thrown upward while in a moving object such as a bus, would be traveling the same speed with respect to the bus and would fall again in relation to that speed.
Answer:
The example of relative velocity - a boat crosses a river that is flowing at some rate or an aeroplane encountering wind during its motion.
Un alumno menciona que al abrir la ventana de su casa sintió cómo el frío ingresaba a su cuerpo. Menciona cuál es la verdadera razón por la cual el niño tuvo la sensación de frío. *
a) Porque el aire tiene una temperatura menor que la de su cuerpo; por eso se propaga más rápido.
b) Porque la temperatura de su cuerpo, siente el aire frio que entra por la ventana.
c) Porque el calor de su cuerpo se propaga al medio ambiente, al ser la temperatura del niño mayor que la del aire exterior.
d) Porque la temperatura del aire es igual a la temperatura del cuerpo.
Answer:
My believe the answer is
A.) or B.)
Explanation:
Here is why I think A is the answer.
If we use the process of elimination, it would look like this,
a) Porque el aire tiene una temperatura menor que la de su cuerpo; por eso se propaga más rápido.
This makes sense because we all know in winter the weather is very cold and freezing.
b) Porque la temperatura de su cuerpo, siente el aire frio que entra por la ventana.
I feel like this answer is the question, but it could also be an answer, sorry, I'm a little uncertain.
c) Porque el calor de su cuerpo se propaga al medio ambiente, al ser la temperatura del niño mayor que la del aire exterior.
This answer has nothing to do with the question, plus it is very false, our body heat is not enough to overcome the very cold temperature from outside.
d) Porque la temperatura del aire es igual a la temperatura del cuerpo.
This is false because again our body heat is not even compared to the freezing cold temperatures from the winter.

39 liters of water at
20 °C are mixed with
21 liters of water at
60 °C. What is the
temperature of the
mixture?
Answer:
Temperature of the mixture=8 °C
Explanation:
Let, Temperature of the mixture=t °C
Q₁ = Q₂
=> m₁SΔΘ₁ = m₂SΔΘ₂
=> 39 × (20+t) = 21 × (60-t)
∴ t = 8 °C

6. 498.82 mg comverted to kg
Answer:
0.00049882 kg
........................
Answer:
498.82 mg=0.00049882 kg
Explanation:
To get this answer, you must multiply the quantity of mg by 0.000001, which is also 0.001². Since one gram is 1000 mg, and 1000 g is 1 kg, you must divide the amount of mg by one million, or multiply by 1/1000000, or 0.000001. I hope this helped you. Enjoy your day, and take care!
The P.E stored by a mass spring system at an extension of 2 cm is 10 J. The P.E stored by the same system at an
extension of 4 cm will be:
Explanation:
extension(x) = 0.02m When the P.E is 10J.
extension(x)= 0.04m PE?.
P.E is proportional to Extension²
P.E/x² = P.E"/x"²
10/(0.02)² = P.E/(0.04)²
P.E= 10x(0.04)²/(0.02)²
P.E= 40J
Is it possible for two different objects to have the same speed but different velocities? Explain your answer.
Yes
Explanation:
Objects have the same velocity only if they are moving the same speed and in the same direction. objects moving at different speeds, in different directions or both have different velocities
Answer:
yes
Explanation:
speed and velocity are the same thing, except that velocity includes a direction.
ex.
if two things are traveling at 3mi/h, then thats the same speed. but if one is going north and the other south, then those are two different velocities

If Bert the Bat travels eastward at 40 mph with a tailwind of 6 mph, what is his actual speed?
Answer:
36 mph.
Explanation:
Now Albert here is using the wind to his advantage but if say there was no wind then he would not have the 6 mph behind him so we subtract 6 from 40 to get 36. hope this helps :)
A hydraulic lift has pistons with diameter 28cm and 70cm, respectively. If a force of 500 N is exerted at the input piston. What is the maximum load that can be lifted the output piston?
Answer:
3125 N
Explanation:
diameter /2 =radius
so r1 =14cm , r2 =35cm
f1/A1 =f2/A2.
f2 = f1 × A2 / A1
=500×1225 pi cm² / 96 pi cm²
f2 =3125N
