Because there is no wind, snow, rain, sleet, blowing dust, hail,
or humidity on the moon to smooth them over and fill them in.
Without those things, we'd be able to see all the ancient meteor
collisions on Earth.

Answer:
44.85C
Explanation:
Let the specific heat of glass thermometer be 0.84 J/g°C
Let the specific heat of water be 4.186 j/g °C
Let the water density be 1kg/L
136 mL of water = 0.136L of water = 0.136 kg of water = 136 g of water
Since the change of temperature on the glass thermometer is 43.6 - 22 = 21.6 C. We can then calculate the heat energy absorbed to it:
Assume no energy is lost to outside, by the law of energy conservation, this heat energy would come from water
Answer:
Explanation:
Using the equation of motion v = u + at to get the speed at which the object would be travelling.
v is the final speed (in m/s)
u is the initial velocity (in m/s)
a is the acceleration (in m/s²)
t is the time taken (in secs)
Given parameters
u = 0m/s
t = 10s
a = g = 9.8m/s²
Substituting this values into the formula;
v = 0+9.8(10)
v = 0+ 98
v = 98m/s
<em>Hence the rock will be travelling at a speed of 98m/s.</em>
The Coulomb's force acting between two charges is
where
is the Coulomb's constant, q1 and q2 the two charges, and r the distance between them.
Using
, we can find the distance between the two charges when the force is F=19.2 N:
