Answer: Noah's speed is 20km/hr
Explanation:
Given;
Final Distance between them at 5pm =320km
Time of travel = 5pm - 1pm = 4 hours
Let x represent Noah's speed
The Ryan's speed = 3x
Total distance between them in 4hours given that they are traveling at opposite directions is.
Distance = speed × time
(x + 3x) × 4hours = 320km
4x × 4 hours = 320km
x = 320km/(4×4hours)
x = 20km/hr
Noah's speed is 20km/hr
Answer:
The correct answer is - B ≠ 0, E = 0.
Explanation:
A force q E is exerted by the electric field on the charged particle that accelerates always, that is, it increases the speed of the particle. The particle can never be rotated in a rotation in the circle in an electric field.
The magnitude of the velocity cannot be changed by the magnetic field but changes only the velocity of the direction.
If the particle moves in a circle it means that the speed should begin for a year. The only direct velocity is constant and only the change be b can be achieved. So, B ≠ 0 and E = 0.
Answer:
These smaller plates are often not shown on major plate maps, as the majority do not comprise significant land area. For purposes of this list, a minor plate is any plate with an area less than 20 million km2 but greater than 1 million km2.

Explanation:
unit of pressure is the system is the Paschal (pa), Newton per square meter
Answer:
70 cm
Explanation:
0.5 kg at 20 cm
0.3 kg at 60 cm
x = Distance of the third 0.6 kg mass
Meter stick hanging at 50 cm
Torque about the support point is given by (torque is conserved)
The position of the third mass of 0.6 kg is at 20+50 = 70 cm
