Answer:

False

Explanation:

In science, Hypothesis  is not an established theory it is just a supposition. It is not necessary that a hypothesis must be true because it is an assumption or an idea which is always tested with an experiment. After carrying out an experiment it can be determined whether the hypothesis is true or false.

Example:

De-Broglie Hypothesis:

De-Broglie gave an hypothesis that light is not a wave nor it posses particle nature but it posses duel nature. According to De-Broglie hypothesis with each moving particle a wave is associated.

But after experiment it is found that with each moving particle a single wave is not associated but a group of wave is associated.

In this way we can say that hypothesis is not always true.

That's false.  A hypothesis may be accurate or full of beans.  That's why you do experiments, to test it.

Cars A and B are racing each other along the same straight road in the following manner: Car A has a head start and is a distanc
kumpel [21]

Answer:\frac{D_A}{v_B-v_A}

Explanation:

Given

car A had a head start of D_A

and it starts at x=0 and t=0

Car B has to travel a distance of D_A and d_a

where d_a is the distance travel by car A in time t

distance travel by car A is

d_a=v_A\times t

For car B with  speed v_B

d_B=D_A+d_a

v_B\times t=D_A+v_A\times t

t=\frac{D_A}{v_B-v_A}

If an electromagnetic wave has components Ey = E0 sin(kx - ωt) and Bz = B0 sin(kx - ωt), in what direction is it traveling?
fomenos

Answer:

Its traveling in the +x direction

Explanation:

The E-field is in the +y-direction, and the B-field is in the +z-direction, so it must be moving along the +x-direction, since the E-field, B-field and the direction of moving are all at right angles to each other.
