Answer:

option C

Explanation:

Before proceeding into an intersection at green signal you should look left, right then left.

According to the question,

while proceeding into intersection at green signal one should look for the vehicle waiting to turn left.

so, the option which is most suited for the question is option C

Vehicles in the intersection waiting to turn left.

Compare and contrast the shape and volume of each state of matter

Inessa [10]

Answer:

Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.

_________ is a change in the position of a body with respect to time relative to a reference point.

rjkz [21]

Answer:

Rest

Explanation:

Rest is a change in the position of a body with respect to time relative to a reference point. The stationary state of an object or body relative to a reference position or another object is called Rest.

Taking Newton's First Law of motion into consideration, an object will remain in its state of rest or uniform motion until acted upon by an external force. This implies an object at rest is an object with zero (without) velocity and acceleration.

The plane of a5cm*8cm rectangular loop of wire is parallel to a 0.19T magnetic field the loop carries a current of 6.2 A. What t

Sedaia [141]

Answer:

Torque; τ = 4.712 × 10^(-3) J

Magnetic moment; M = 0.0248 J/T

Explanation:

Torque is gotten from the formula;

τ = BIA

Where;

B is magnetic field

I is current

A is area

We are given;

B = 0.19T

I = 6.2A

Rectangle dimensions = 5cm by 8cm = 0.05m by 0.08m

Thus;

Area; A = 0.05m × 0.08m = 0.004 m²

Thus;

τ = 0.19 × 6.2 × 0.004

τ = 4.712 × 10^(-3) J

Formula for the magnetic moment is given by;

M = IA

M = 6.2 × 0.004

M = 0.0248 J/T

andreev551 [17]

Answer: R=24.2Ω

Explanation: Power is rate of work being done in an electric circuit. It relates to voltage, current and resistance through the following formulas:

P=V.i

P=R.i²

$P=\frac{V^{2}}{R}$
