A particle whose speed is 50 m/sec moves along the line from A(2,1) to B (9,25)

WINSTONCH [101]

First, calculate for the distance between the given points A and B by using the equation,

D = sqrt ((x2 – x1)2 + (y2 – y1)2)

Substitute the known values:

D = sqrt((9 – 2)2 + (25 – 1)2)

D = 25 m

I assume the unknown here is the time it would require for the particle to move from point A to B. This can be answered by dividing the calculated distance by the speed given above.

t = (25 m)/ (50 m/s) = 0.5 s

Thus, it will take 0.5s for the particle to complete the route.

You short-circuit a 18 volt battery by connecting a short wire from one end of the battery to the other end. if the current in t

mina [271]

The relationship between the voltage and the current in the circuit is:
$\Delta V = RI$
where $\Delta V$ is the voltage difference, R the resistance of the circuit (and therefore, the resistance of the battery) and I the current flowing in the circuit. By using I=19 A and $\Delta V = 18 V$ , we can find the internal resistance of the battery:
$R= \frac{\Delta V}{I}= \frac{18 V}{19 A}=0.95 \Omega$

A copper wire 12 cm long and a mass of 16 g is in a magnetic field of 1.2 T oriented perpendicular to the wire. What current wou

Ugo [173]

Answer:

Current, I = 1.08 A

Explanation:

Given that,

Length of the copper wire, l = 12 cm = 0.12 m

Mass of the wire, m = 16 g = 0.016 kg

Magnetic field, B = 1.2 T

The magnetic field is oriented perpendicular to the wire. We need to find the current in the wire.

Magnetic force, F = BIL

Force of gravity, F' = mg

F' = F

$BIL=mg$

$I=\dfrac{mg}{BL}$

$I=\dfrac{0.016\times 9.8}{1.2\times 0.12}$

I = 1.08 A

So, the current through the wire is 1.08 A. Hence, this is the required solution.
