Mathematics is a broad subject that anyone who constantly practices by learning from first principle and from example will grow in perfection of the subject as time goes by. Hence, I strongly disagree

During my schools days, I struggled learning mathematics, at the time it was difficult, I began practising and learning from text examples, with time I got a hang of it and my grade and confidence level in the subject increased.

A uniform electric field (constant in magnitude and direction) exists in the region between two oppositely charged plane paralle

Over [174]

Answer:

Part a)

$E = 39.7 N/C$

Part b)

$v_f = 1.10\times 10^4 m/s$

Explanation:

Part a)

Proton is released from one plate and strike at other plate in time

$t = 2.90 \times 10^{-6} s$

$d = 1.60 cm$

now we will have

$d = \frac{1}{2}at^2$

$0.0160 = \frac{1}{2}a(2.90 \times 10^{-6})^2$

$a = 3.8 \times 10^9 m/s^2$

now we know that

$a = \frac{qE}{m}$

$3.8 \times 10^9 = \frac{(1.6 \times 10^{-19})E}{(1.67 \times 10^{-27})}$

$E = 39.7 N/C$

Part b)

Speed of the proton when it strike the other plate can be calculated by kinematics equations

$v_f^2 - v_i^2 = 2ad$

$v_f^2 - 0 = 2(3.8 \times 10^9)(0.0160)$

$v_f = 1.10\times 10^4 m/s$

What factors cause friction and thermal energy to increase? I need help ASAP!

VladimirAG [237]

Explanation:

Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

How long does it take a car to go 1000 m if it is going at 50 m/sec?

Lina20 [59]

The car would take 20 seconds to go 1000 meters. This can be found by dividing 1000 by 50.
