Answer: Protons
Explanation: The atomic number is the number of protons that are in the nucleus of an atom. Each element on the periodic table is defined by the number of protons. In other words, the protons/atomic number determines what element it is. Protons carry a positive charge.
First find the time it takes to hit the sand t
using s=1/2 g t^2
t^2= 8/9.8= 0.82 seconds
This means the sand was s = 8 * 0.82 = 6.5m away
The horizontal speed stays constant at 8 m/s
The vertical speed =.82 * 9.8 = 8.0 m/s
As the two velocities are equal the angle must be 45 degrees to the horizontal
Answer:
Explanation:
a ) At constant pressure , work done = P x Δ V
= 200 x 10³ x ( .1 - .04 )
= 12 x 10³ J .
b )
At constant temperature work done
= n RT ln v₂ / v₁
= PV ln v₂ / v₁
= 200 x 10³ x .04 ln .1 / .04
8 x 10³ x .916
= 7.33 x 10³ J .
Closer orbit less distance to travel round shorter time taken for complete orbit. further orbit further to travel longer time for complete orbit
