Answer:
2 /s north
Explanation:
Given that,
Velocity due North is 8 m/s and due south is 6 m/s
We need to find the magnitude and the direction of the resulting velocity.
Let North is positive and South is negative. When two velocities are in opposite direction, they adds up. So,
It is positive. So, it is in North direction.
Q2 is 1.60x10^-19.
because if you round up or add, you will come with q2
Answer:
Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.
Answer:
a. reflection of all the light at a surface.
Explanation:
When light rays passing from the denser medium to the rarer medium and the angle of incidence is greater than the critical angle, the refraction of light does not take place and the incident ray is totally reflected back into the denser medium. This phenomenon is called total internal reflection.
There are two conditions that need to be fulfilled in order for the total internal reflection to take place:
1. The ray of light should be incident from denser to rarer medium.
2. The angle of incidence should be greater than the critical angle.
Therefore, the correct option will be:
<u>a. reflection of all the light at a surface.</u>
As the gas absorbs heat, the sounds he hears become softer. This is because the pressure of the neon gas inside the container increases when the gas gets warmer, the walls of the container become tighter and stiffer, and it's harder for them to vibrate.
