Hello! The answer is B and B.

When a system is in equilibrium, this means that the net force/total force = 0N. Hence you need to add 10N to the 10N force acting towards the right so that the 20N acting in opposite directions will ‘cancel’ out to get a net force of 0N.

Average velocity is calculated by distance travelled divided by time. Hence, velocity = 50m/5s = 10ms^1

Answer:

0 N

Explanation:

Applying,

F = qvBsin∅................. Equation 1

Where F = Force on the charge, q = charge, v = Velocity, B = magnetic charge, ∅ = angle between the velocity and the magnetic field.

From the question,

Given: q = 4.88×10⁻⁶ C, v = 265 m/s, B = 0.0579 T, ∅ = 0°

Substitute these values into equation 1

F = ( 4.88×10⁻⁶)(265)(0.0579)(sin0)

Since sin0° = 0,

Therefore,

F = 0 N

rodikova [14]

Answer:

Rhizobium.

Explanation:

The roots of most of these plants have nitrogen-fixing bacteria known as rhizobium. It helps to change nitrogen which is present in the air into the nitrates which are plants, and that is need to synthesize proteins.

Rhizobium bacteria occupy the root hairs which are present on the plants, they help the plant to grow and keep up with other plants. When the one plant dies, the fixed nitrogen which is present in it will release, and making it available for other plants, and this process helps to fertilize the soil in the environment.
