At a particular instant, a proton at the origin has velocity < 5e4, -2e4, 0> m/s. You need to calculate the magnetic field

vesna_86 [32]

Answer:

$9.7\times 10^{-5} T$

Explanation:

Velocity = $5\times 10^4i-2\times 10^4j$

r= $0.03i+0.05j$

r= $\mid r\mid=\sqrt{(0.03)^2+(0.05)^2}=0.058$

v= $\mid V\mid=\sqrt{(5\times 10^4)^2+(-2\times 10^{4})^2}=5.39\times 10^{2}$

We know that

$B=\frac{mv}{qr}$

Where q= $1.6\times 10^{-19} C$

Mass of proton= $1.67\times 10^{-27} kg$

Using the formula

$B=\frac{1.67\times 10^{-27}\times 5.39\times 10^2}{1.6\times 10^{-19}\times 0.058}$

$B=9.7\times 10^{-5} T$

A jet’s original velocity is 600 m/s. After 20 seconds accelerating at 8 m/s 2 , how

scoray [572]

Answer:

Explanation:

The jet's speed or final velocity can be found by using the formula

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

From the question we have

v = 600 + 20(8)

= 600 + 160

We have the final answer as

Hope this helps you
