Answer:
The maximum height of the ball will be "16.53 m".
Explanation:
Given that,
As we know,
The initial as well the final height on the ball will be same after it reaches it's maximum height.
then,
⇒ 
where, 
hence,
The max height of the ball will be:
⇒ 
Answer:
a) 17.33 V/m
b) 6308 m/s
Explanation:
We start by using equation of motion
s = ut + 1/2at², where
s = 1.2 cm = 0.012 m
u = 0 m/s
t = 3.8*10^-6 s, so that
0.012 = 0 * 3.8*10^-6 + 0.5 * a * (3.8*10^-6)²
0.012 = 0.5 * a * 1.444*10^-11
a = 0.012 / 7.22*10^-12
a = 1.66*10^9 m/s²
If we assume the electric field to be E, and we know that F =qE. Also, from Newton's law, we have F = ma. So that, ma = qE, and E = ma/q, where
E = electric field
m = mass of proton
a = acceleration
q = charge of proton
E = (1.67*10^-27 * 1.66*10^9) / 1.6*10^-19
E = 2.77*10^-18 / 1.6*10^-19
E = 17.33 V/m
Final speed of the proton can be gotten by using
v = u + at
v = 0 + 1.66*10^9 * 3.8*10^-6
v = 6308 m/s
Answer:
both are 45√2N
Explanation:
90 sin45°=90 cos45°=45√2N
B. It measures <span>changes in the variable that is being controlled
</span>The receptor senses environmental stimuli, sending the information to the integrating center.
The only common property is that both of those things are comprised of H2O.
