It doesn't exist ! But if you wanna say milimeters, you only have to move the comma on the left 6 times.

What is the direction of propagation of the wave if E⃗ =Ei^,B⃗ =−Bj^. Express the direction of the propagation vector, P⃗ , as a

nataly862011 [7]

Answer with Explanation:

We are given that

Electric field vector= $\vec{E}=E\hat{i}$

Magnetic field vector= $\vec{B}=-B\hat{j}$

We have to find the direction of propagation of the wave.

We know that

The direction of propagation of wave= $\vec{E}\times \vec{B}$

The direction of propagation of wave= $\hat{i}\times (-\hat{j})=-\hat{k}$

Because ( $\hat{i}\times \hat{j}=\hat{k}$ )

The wave propagate in -z direction.

Therefore, the component of the vector is (0,0,-1).

Hence, the direction of the propagation of wave is - z direction and component of direction of propagation vector is (0,0,-1).

You push a 50 kg wooden box across a wooden floor at a constant speed of 1.0 m/s. The coefficient of kinetic friction is 0.15. N

WARRIOR [948]

Answer:

0.68 seconds

Explanation:

Data provided in the question:

Mass of the box = 50 kg

Speed of the box = 1.0 m/s

Coefficient of friction, μ = 0.15

Now,

Force applied = μmg

Here,

g is the acceleration due to gravity = 9.8 m/s²

Thus,

F = 0.15 × 50 × 9.8

= 73.5 N

Also,

Force = Mass × Acceleration

thus,

73.5 N = 50 × a

a = 1.47 m/s²

After doubling the speed

Final speed = 2 × Initial speed

= 2 × 1 m/s

= 2 m/s

Also,

Acceleration = [change in speed] ÷ Time

1.47 = [ 2 - 1 ] ÷ Time

Time = 1 ÷ 1.47

Time = 0.68 seconds
