Answer
given,
Electric field,E = 490 N/C
time, t = 54 ns
for electron
Mass of electron me = 9.1 x 10⁻³¹ kg
Charge of electron e = -1.6 x 10⁻¹⁹ C
electrostatic force
F = E q
F = 490 x 1.6 x 10⁻¹⁹
F = 784 x 10⁻¹⁹ N
now, using newton second law
a = 8.62 x 10¹² m/s²
using equation of motion
v = u + a t
v = 0 + 8.62 x 10¹² x 54 x 10⁻⁹
v = 4.65 x 10⁵ m/s
velocity of electron is equal to v = 4.65 x 10⁵ m/s
For Proton
Mass mp = 1.67 x 10⁻²⁷ kg
Charge p = 1.6 x 10⁻¹⁹ C
Electric field E = 490 V/C
from above solution
F = 784 x 10⁻¹⁹ N
now, acceleration
a = 4.69 x 10¹⁰ m/s²
using equation of motion
v = u + a t
v = 0 + 4.69 x 10¹⁰ x 54 x 10⁻⁹
v = 4.65 x 10³ m/s
velocity of electron is equal to v = 4.65 x 10³ m/s

Hi there!
Momentum (p) = m · v
Calculate for each:
Table tennis ball: p = 0.003 kg × 16 m/s = <em>0.048 kgm/s</em>
Soccer ball: p = 0.43 kg × 16 m/s = <em>6.88 kgm/s</em>
<em></em>
The momentum of the soccer ball is GREATER THAN the momentum of the table tennis ball.
Answer:
False
Explanation:
Using your opposite hand will strengthen neural connections in your brain, and even grow new ones. It’s similar to how physical exercise improves your body’s functioning and grows muscles
