Answer:
A True ( I Think Its True I'm Not Intirely sure)
Explanation:
All electromagnetic waves travel at 3*10^8 ms⁻¹ , the equation for wave speed is v=wavelength*frequency. Therefore wavelength=v/f=3*10^8/600000000=0.5m
Answer:
Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials.
A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress.
Compression squeezes rocks together, causing rocks to fold or fracture (break) (Figure below). Compression is the most common stress at convergent plate boundaries.

Answer:
The potential energy of the electron in the field of the positive proton point charge is U(r) = -qeV(r) = - keqe2/r. The total energy is the sum of the electron's kinetic energy and its potential energy.
Explanation:
In each case the origin is located at the intersection of the axes. The electric potential from a single charge is defined to be zero an infinite distance from the charge, and the electric potential associated with two charges is also defined to be zero when the charges are infinitely far apart.
The girls distance is 50 km in 2 hours.
