A proton beam in an accelerator carries a current of 130 μa. if the beam is incident on a target, how many protons strike the ta

Ivanshal [37]

The current intensity is the product between the total charge that flows through a certain point (in our case, the target) in a time interval $\delta t$ :
$I= \frac{Q}{\Delta t}$
We know the current, $I=130 \mu A=130 \cdot 10^{-6} A$ , and the time interval, $\Delta t=17 s$ , so we can find the total charge:
$Q=I \Delta t= 2.21 \cdot 10^{-3}C
$

The total charge Q is the product between the number of protons N and the charge of each protons, e, which is $e=1.6 \cdot 10^{-19}C$ :
$Q=Ne$
we can re-write the equation solving for N, so we can find the number of protons striking the target in 17 s:
$N= \frac{Q}{e}= \frac{2.21 \cdot 10^{-3}C}{1.6 \cdot 10^{-19}C} =1.38 \cdot 10^{16}$

A 1kg object loses 20 j of gpe as it falls how far does it fall

jarptica [38.1K]

Gravitational potential energy (GPE) is energy within an object with respect to its height. The equation of gpe is:

GPE = mgh

where:
m = mass of object
g = gravitational constant, 9.81 m/s^2
h = height

For a given gpe of 20 J, the height can be calculated as follows:
*Remember to be consistent with units. Since Joule is derived from SI units, make sure to use SI units for the other variables

GPE = 20 J = 1 (9.81) (h)
h = 2.04 meters

A car is travelling at a constant speed of 26.5 m/s. Its tires have a radius of 72 cm. If the car slows down at a constant rate

maksim [4K]

Answer:

Magnitude of angular acceleration = -3.95 rad/s²

Explanation:

Angular acceleration is the ratio of linear acceleration and radius.

That is

$\texttt{Angular acceleration}=\frac{\texttt{Linear acceleration}}{\texttt{Radius}}\\\\\alpha =\frac{a}{r}$

Radius = 72 cm = 0.72 m

Linear acceleration is rate of change of velocity.

$a=\frac{11.7-26.5}{5.2}=-2.85m/s^2$

Angular acceleration

$\alpha =\frac{a}{r}=\frac{-2.85}{0.72}=-3.95rad/s^2$

Angular acceleration = -3.95 rad/s²

Magnitude = 3.95 rad/s²

Defined the term electromagnetic induction and explain how a generator uses electromagnetic induction

tatuchka [14]

Is the production of electricity by magnetic field.

There are two types of generator which is D.C generator . And A.C generator

A.C gen consist of rectangular coil,brushes and permanent magnet

According to the external force mechanical energy used to rotate coil, due to magnetic flux produced by permanent magnet create induced current, this is to according to flemmings right hand rule of electromagnetic induction the rotating coil will produce current

I hope that will help.
