Answer:
Use a yellow (Red + Green) spotlight to make it look black.
Explanation:
The blue fabric has pigments that can absorb the red and green light. This light is incident on the fabric, therefore, there is no light left to be reflected back, so, at plain sight, the dress will look black.
kg are units of mass. The acceleration on the moon due to gravity is roughtly 1/6 that of earth. A more precise figure is 1.62 m/s^2
a = 1.62 m/s^2
m = 83 kg
F = ?
F = m * a
F = 83 * 1.62
F = 134.46 Moon's gravitational force on 83 kg man
On earth the force would be 83 * 9.81 = 814.23 Newtons.
the man would only weigh 13.7 kg on the moon
hope i helped:)
the answer is the car traveled 5km.
I know because i took the test a few weeks ago and got an A on it
sorry im late
oh and just remeber to put the answer i your own words and show show you got it.
hope this helps
opposite to the net force
left
opposite to motion
The friction arrow in an FBD for a moving object point is in opposite way to motion. Because friction always works in the opposite direction of the motion of the object.
Answer: Option D
Explanation:
When two object come into contact, the contact force come into play. Now, one component of the contact force i.e. the normal forces act perpendicularly at the direction of motion. Whereas, the frictional forces always acts parallel at the direction of the force acting on the object but in the opposite way.
For example, if we slide a book on the table to the right hand side, the exact equal and opposite frictional force will induce in the opposite direction, tempting to reduce the motion.
The more energy in a wave, the higher its frequency. The lower the frequency is, the less energy in the wave.
