Answer:

C. It is negative

Explanation:

Per Newton's second law, the net force is the mass times the acceleration:

∑F = ma

If the acceleration is negative, the net force is negative.

Answer:

C. It is negative

Explanation:

As we know that mass of the bike is given as

m = 40 kg

now we know by Newton's law of motion

F = ma

here we know that

m = mass of the bike

a = acceleration of the bike

so here we will have

F = 40 (a )

now if the acceleration of the bike is in negative direction

then we will get a negative force on it as per above formula

so correct answer will be

C. It is negative

How does Electromagnetic Energy Travel?
alisha [4.7K]

Answer:

Perpendicular to the electric field and magnetic field

Explanation:

Electromagnetic waves are transverse waves composed by the perpendicular oscillating electric and magnetic fields.

EM waves have both Electrical and magnetic features.

they travel in the velocity of light (3*10⁸ ms⁻¹)

they does not require any media to travel. It has two perpendicular electric field and the magnetic field which are perpendicular to each other

They travel perpendicular to each of those electric and magnetic fields.
