Three long, straight wires are carrying currents that have the same magnitude. In C the current is opposite to that in A and B.

Nadusha1986 [10]

Answer:

(b) B

Explanation:

The direction of force on a current carrying wire in a magnetic field can be found using the right hand rule, which states that-"stretch the thumb in the direction of the current, and point the fingers in the direction of magnetic field. The direction of palm will then give the direction of force on the wire

On wire B the forces due to A and C act in the same direction and so strengthen each other. they get added up because the forces act in the same direction.

on wires A and C the forces (due to B and C and A and B

respectively) act in opposite directions and therefore tend to cancel out.

How much heat is needed to raise the temperature of 8g of water by 15oC?

Murrr4er [49]

<h2>Answer: 502.08 J</h2>

Explanation:

The heat (thermal energy) needed in to raise the temperature in a process can be found using the following equation:

$Q=m.C.\Delta T$ (1)

Where:

$Q$ is the heat

$m=8 g$ is the mass of the element (<u>water</u> in this case)

$C$ is the specific heat capacity of the material. In the case of water is $C=4.184\frac{J}{g\°C}$

$\Delta T=15\°C$ is the variation in temperature <u>(which is increased in this case)</u>

Knowing this, let's rewrite (1) with these values:

$Q=(8 g)(4.184\frac{J}{g\°C})(15\°C)$ (2)

Finally:

$Q=502.08 J$

A swing that is 9.2m long has a child in it who is swinging. what is its period in seconds

Fantom [35]

The child on a swing can be modeled as a simple pendulum. The period of a simple pendulum is given by

$T=2 \pi \sqrt{ \frac{L}{g} }=2 \pi \sqrt{ \frac{9.2m}{9.8 \frac{m}{s^2} } }=6.09s$

If a football quarterback can throw the ball at 20.0 m/s, what is the furthest distance the quarterback could throw the ball neg

kvasek [131]

The furthest distance the quarterback could throw the ball neglecting air resistance is 81.63 meters.

The situation given above is an example of projectile motion.

The maximum distance up to which a projectile can be thrown is known as its range, which is given by the formula,

Range(R) = 2u^2 sin(2θ)/g

Here u is the maximum velocity of the projectile= 20 m/s

θ is the angle at which the projectile is launched = 45°

g is the acceleration due to gravity = 9.8 m/s^2

Putting the above values in the given equation,

The range comes out to be 81.63 meters.

Hence, the furthest distance the quarterback could throw the ball neglecting air resistance is 81.63 meters.
