Answer:
g, downward
Explanation:
It is given that, a baseball is thrown straight upward. The force acting on the stone is force of gravity. It is moving under the action of gravity. We know that the force of gravity always acts in a downward direction.
At the highest point, the velocity of the stone will be equal to 0. It will move will constant acceleration equal to g and it always acts in downward direction.
Hence, the correct option is (e) "downward direction".
Answer:
We usually travel in January or Feb for our tropical get-a-way. For those of you that have traveled in the fall and winter...
What is the real difference...Like in the floral and fauna, weather, and the capacity of the resorts between these 2 times of the year.
In this equation
1 Cl2 + 3 F2---> 2 ClxFy
those coefficients are in MOLE (or molecule) ratios. BUT for gases at the same temp and pressure, they are also VOLUME ratios.. why? PV = nRT, V = nRT/P. if RT/P = constant.. V1/n1 = V2/n2 --> n1/n2 = V1/V2..make sense? mole ratios
= volume ratios
so.. what are x and y?
1 Cl2 + 3 F2---> 2 ClxFy
2 Cl's on the left.. x must = 1
6 F2's on the left. y must be 3
1 Cl2 + 3 F2---> 2 ClF3

Answer:Im guessing Mechanical Energy
Explanation:
We are learning that work and energy work hand in hand so im completely guessing this
Explanation:
This is simple.
Convert the speed of 45km/h to metres per second (m/s):
45 * 1000m = 45000m per hour.
1 hour = 60 seconds * 60 minutes = 3600 seconds.
45000m/h / 3600 = 12.5m/s
(A quicker way is just to divide by 3.6)
So in 20 seconds it would cover:
12.5m/s * 20s = 250m.
A car travelling at 45km/h would travel 250 metres in 20s.
