The distance travelled by the baseball is 221 m.
<u>Explanation:</u>
Speed is the ratio of distance travelled to the time taken to cover any distance. So here the speed is given as 96 m/s and time is given as 2.3 seconds. Thus, we can determine the distance as product of speed with time.
Thus, distance = speed × Time
As the speed is 96 m/s and time is 2.3 seconds.
The distance = 96 × 2.3 =220.8 m
If we approximate it, the distance is 221 m. Thus, the distance travelled by the baseball is 221 m.
It won't happen anything i think it will just be a something like a small thing
Answer:
C is the best suited to the characteristics given in the question
Explanation:
Agricultural chemistry studies on both agriculture which deals with the production of plants and chemistry which controls the raw materials in food and drinks. Agricultural chemistry also investigates environmental changes and emphasizes the studies to explain interactions between plants and animals in nature.
Answer:
even if it all could be used, it wouldn't be enough
Explanation:
The land area of the US is about 5.45% of the world's area, so the amount of released heat over the area of the US is on the order of 2.4 Tw. Current technology for converting geothermal energy to electricity is about 12% efficient, so the available energy might amount to 0.29 Tw if it could all be captured.
Energy consumption in the US in 2019 was on the order of 0.46 Tw. This suggests that even if <em>all</em> of the thermal energy radiated by the Earth from the US could be turned to useful forms of energy, it would meet only about 60% of the US need for energy.
The wavelength is equal to Planck's constant divided by the ball's momentum.
This means that:
lambda = h / p .............> equation I
Momentum = mass * velocity ............> equation II
Substitute by equation II in equation I, you get:
lambda = h / mv
Now, we are given:
lambda = 8.92 * 10^-34 m
Planck's constant = 6.625 * 10^-34
velocity = 40 m/sec
Substitute with these givens in the above equation to calculate the mass as follows:
8.92*10^-34 = (6.625*10^-34) / (40*m)
mass = 0.0185678 kg
