Due to its polarity and hydrogen bonding water can absorb heat without a significant temperature change.. The high specific heat of water helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual instead of sudden, especially near the oceans.

To find this value, you need to remember the speed formula:
3 = 6 / 2
Speed = distance ÷ time
Rearrange to make distance the subject:
Distance = speed * time
Simply plug these values into this:
5.6 * 8.25 = 46.2
<h3>So the player will travel 46.2 metres!</h3>
<h2>Hope this helps!</h2>
Under constant acceleration, we have average velocity over a time interval of duration satisfying
where are the plane's initial position and velocity (respectively) and are the plane's position and velocity (respectively) after 9.00 seconds. So
Answer: -10N
Explanation:
Given that,
negative charge (q1) = -2 C
positive charge (q2) = 4 C
Distance between charges (r) = 84,681 m
force between the two charges (F) = ?
Apply the formula for
F= (kq1q2) / r^2
Recall that k is Coulomb's constant with a value of 9 × 10^9 Nm2C−2
Then,
F = (9 × 10^9 Nm2C−2 x -2C x 4C) / (84,681 m)^2
F = (-7.2 x 10^10) / (84,681 m)^2
F = -9.998N (Rounded up to nearest whole number as -10N)
Thus, the force between the two charges is -10 newton
Answer:
Wavelength is calculated as 213.9 nm
Solution:
As per the question:
Wavelength of light = 570 nm
Time, t = 16.5 ns
Thickness of glass slab, d = 0.865 ns
Time taken to travel from laser to the photocell, t' = 21.3
Speed of light in vacuum, c =
Now,
To calculate the wavelength of light inside the glass:
After the insertion of the glass slab into the beam, the extra time taken by light to cover a thickness t = 0.865 m is:
t' - t = 21.3 - 16.5 = 4.8 ns
Thus
where
n = refractive index of the medium
v = speed of light in medium
n = 2.66
Now,
The wavelength in the glass:
