To solve this problem, we use the formula:
F = G m1 m2 / r^2
where F is gravitational force, G is constant, m1 and m2
are masses while r is the distance between the two asteroids
Since G m1 m2 is constant, therefore:
F1 r1^2 = F2 r2^2
So if r2 = 2 r1:
(1,000,000 N) (r1^2) = F2 * (2 r1)^2
<span>F2 = 250,000 N</span>
<span>
</span>
<span>It was divided by 4</span>
Answer:
Each part of the spectrum has a different range of wavelengths (which correspond to frequency, color, and energy) at which you can find it.
First of all the kinetic energy is when the particles move in continuous random motion.
If the temperature is high the colliding particles will collide more. and if the temperature is low the colliding particles will collide less.
Low temperature result in low kinetic energy
High temperature result in high kinetic energy
Absolute zero is the point where where all molecules have no kinetic energy. It is a theoretical value (it has never been reached).
The Kelvin temperature scale is based on absolute zero being the lowest possible temperature that could theoretically be reached. That is why there is no such thing as a negative Kelvin temperature value.
Answer:
C) True. At maximum displacement, its instantaneous velocity is zero.
Explanation:
The simple harmonic movement is given by
x = A cos wt
Speed
v = - A w sin wt
At the point of maximum displacement x = A
A = A cos wt
cos wt = 1
wt = 0
We replace the speed
v = -Aw sin 0 = A w
Speed is maximum
Let's review the claims
A) False. Speed is zero
B) False. It can be determined
C) True. Agree with our result
D) False. When one is maximum the other is minimum
Years of research have demonstrated that rats are intelligent creatures who experience pain and pleasure, care about one another, are able to read the emotions of others, and would assist other rats, even at their own expense.
<h3>Experiments:</h3>
In trials carried out at Brown University in the 1950s, rats were trained to press a lever for food, but they stopped pressing the lever when they noticed that with each press, a rat in an adjacent cage would scream in pain (after experiencing an electric shock).
Rats were trained to press a lever to lower a block that was hanging from a hoist by electric shocks administered by experimenters. A rat was subsequently hoisted into a harness by the experimenters, and according to their notes, "This animal normally shrieked and wriggled sufficiently while dangling, and if it did not, it was jabbed with a sharp pencil until it exhibited indications of discomfort." Even if it wasn't in danger of receiving a shock, a rat watching the scenario from the floor would pull a lever to lower the hapless rodent to safety.
