Answer:
Water has higher specific heat capacity compared to copper. This means that water needs to absorb more heat energy to increase it's temperature by 1 °C. Therefore, water needs longer time to release heat energy due to higher amount of heat energy stored inside the water.

what happens when air filled balloon is left with its mouth downwards and allowed the air to escape
Answer:
As their is a high pressure inside the balloon, air would gush out of the ballon.
Due to Newton's Third Law of Motion, When this air exerts a force downwards , the surrounding medium would also exert an equal and opposite force on the ballon.. due to which it would fly upwards.

What is the magnitude? PLSSS HELP (15 POINTS)!!
Answer:
i think the answer is -3m/s2 as there written no sign so it will be 3m/s2
Explanation:
we can see its an uniform decelaration
so we know
a=v-u/t
or a=2-26/8-0
so a =-24/8
so a=-3m/s2
how do you find your spirit animal?
Answer:
Take a Buzzfeed quiz
Explanation:
I doubt finding your spirit animal is easy, so you must consult the infamous website known for random personality quizes, Buzzfeed.
I'm sure there will be many quizes focused on the exploration of spirit animals, and finding yours with accuracy is something Buzzfeed takes pride in, (despite the fact that this is a comercial buisness with the only intent of making money off of your personality quiz exploits) so your spirit animal should be found with ease.
If Buzzfeed turns out to be unsucsessful, I recomend just searching up your question online to find countless other resources dedicated to your spirit animal journey.
You could also consult your local witch to see if they know anything about spirit animals.
Answer:
i will tell you how to do it because i've done it before
Explanation:
So to find your spirit animal you don't choose it. It chooses you. To find yours it can be in your dreams, daydreams. Look into your concious. In your dreams look at the animals to see if there is anything unusal about them that is out of the ordinary. It will show itself to you in ways you might not realize. If you do see an animal out of the ordinary, inspect it, try asking it something, because if it shows itself to you that means it is willing to guide you. Thats what your spirit animal is for.

Since kinetic energy depends on mass and speed, will a 300-pound baseball player hit the ball farther than a 100-pound baseball player? EXPLAIN
Assume the following conditions in this scenario:
1. The bat is identical in mass and weight for both players
2. both players swing the bat with the same velocity
3. The weather conditions are identical for both players (wind, climate etc..)
4. both players meet the ball squarly so as to hit the ball in the same place for the best outcome
It's definitely a Physics question !
Here's how I would look at it:
The player doesn't hit the ball. The bat does.
You said that the two bats are identical, and both players swing the bat with the same speed.
So at the point where the bat meets the ball, the conditions are the same both times.
The ball can't tell the difference.
Its history will unfold identically after both hits.
what property of light is suggested by the formation of shadows
Answer:
Please mark me as the brainliest
Explanation:
The way shadows are formed in such a way that the shape of the shadows resembles the object is because light travels in straight lines. This means that, a light ray wouldn't just jump up the obstacle and land on the other side and then you would see some funny light spots on the shadow
An object accelerates from rest with a constant acceleration of 7.5 m/s2. How fast will it
be traveling after it goes 12 m?
Answer:
13.4 m/s
Explanation:
Given:
Δx = 12 m
v₀ = 0 m/s
a = 7.5 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (0 m/s)² + 2 (7.5 m/s²) (12 m)
v ≈ 13.4 m/s

A roller coaster pushes a 25 kg person upward with a force of 300 N. What is the acceleration?
Answer: a=F/m , a = 300N/25N , a= 12 m/s2
Explanation: Divide the 300 by 25 you get 12 . If your wondering how i got 25N in the eqaution it because you change 25kg to 25N. I hope this helps you
Acceleration of an object is the force divided by mass. The acceleration of the roller coaster to push the 25 kg person with a force of 300 N is 12 m/s².
What is acceleration ?Acceleration is a physical quantity measuring the rate of change in velocity. It is a vector quantity having both magnitude and acceleration. Acceleration has the unit of m/s².
According to Newton's second law of motion, the force acting on a body is the product of its mass and acceleration.
F = ma
Given that, mass of the person = 25 kg
force applied on the body = 300 N
acceleration = force/mass
a = 300 N/25 kg = 12 m/s²
Therefore, the acceleration of the roller coaster is 12 m/s².

Answer:
I think C like my friend upove
Explanation:
help me please, i need it fast
Answer:
2) C. (x - 3)² + (y + 2)² = 25
5) x² + y² - 8x - 16y + 54 = 0
6) x² + y² - 10x - 12y + 36 = 0
Explanation:
2)
center of circle = 3, -2
x1, y1
end point of circle = 7, 1
x2, y2
the equation of a circle is Pythagorean theorem
x² + y² = r² (where r is the radius of a circle)
distance between points
(x2 - x1)² + (y2 - y1)² = r²
(7 - 3)² + (1 - (-2))² = r²
r² = 25
therefore the equation to the circle is
(x - 3)² + (y + 2)² = 25
=========================================
5)
write the general form of a circle with the center (4,8)
and containing the point (-1, 7)
distance between points
(x2 - x1)² + (y2 - y1)² = r²
(-1 - 4)² + (7 - 8)² = r²
r² = 26
(x - 4)² + (y - 8)² = 26
(x - 4)(x - 4) + (y - 8)(y - 8) = 26
x² - 8x + 16 + y² - 16y + 64 -26 = 0
x² + y² - 8x - 16y + 54 = 0
=========================================
6)
find the general form of a circle with center (5,6)
and tangent to the y-axis.
center (5,6)
h, k
radius = r²
r = 5
(x - h)² + (y - k)² = r²
(x - r)² + (y - k)² = r²
(x - 5)(x - 5) + (y - 6)(y - 6) = r²
x² - 10x + 25 + y² - 12y + 36 = 25
x² + y² - 10x - 12y + 36 = 0
