An electron that has a velocity with x component 1.6 × 10^6 m/s and y component 2.6 × 10^6 m/s moves through a uniform magnetic

ioda

Answer:

(a)

$\overrightarrow{F}=4.58\times10^{-14}\widehat{K}N$

(b) $\overrightarrow{F}=- 4.58\times10^{-14}\widehat{K}N$

Explanation:

Vx = 1.6 x 10^6 m/s

Vy = 2.6 x 10^6 m/s

Bx = 0.024 T

By = - 0.14 T

charge of electron, q = - 1.6 x 10^-19 C

charge of proton, q = 1.6 x 10^-19 C

(a) Force on electron is given by

$\overrightarrow{F}=q(\overrightarrow{V}\times \overrightarrow{B})$

Substituting the values

$\overrightarrow{F}=-1.6\times10^{-19}{\left ( 1.6\times 10^{6}\widehat{i}+2.6 \times 10^{6}\widehat{j} \right )\times \left ( 0.024\widehat{i}-0.14\widehat{j} \right )}$

$\overrightarrow{F}=4.58\times10^{-14}\widehat{K}N$

(b) Force on proton is given by

$\overrightarrow{F}=q(\overrightarrow{V}\times \overrightarrow{B})$

Substituting the values

$\overrightarrow{F}=1.6\times10^{-19}{\left ( 1.6\times 10^{6}\widehat{i}+2.6 \times 10^{6}\widehat{j} \right )\times \left ( 0.024\widehat{i}-0.14\widehat{j} \right )}$

$\overrightarrow{F}=- 4.58\times10^{-14}\widehat{K}N$

erma4kov [3.2K]

Answer:

23,49 m/s

Explanation:

Ep= Ek

mgh=mv2/2

6×10×30=6v2/2

1800=6 v2/2

6 v2=3600

v2 =600

A toaster uses 6700 joules of energy in 45 seconds to toast to a piece of bread what is power of the oven

just olya [345]

P= w/t and W= Work
In this case, W= 6,700j, and T= 45 seconds
Power is the ratio of work per unit time. When you perform a work in a given span of time, the ratio of work performed with respect to time is Called Power.
si unit for Power is Watt (W)
so, P= 6,700/45
P= 148
Final answer is P=148
