A) The magnitude of the electric field generated by a single point charge is given by
where k is the Coulomb's constant, q is the charge and r is the distance at which we calculate the field.
Since we want to know the intensity of the field at distance of r=4.52 m from the charge of q=8.15 C, the intensity of the electric field is
b) Direction of the field
The charge that produces the field is negative, and we know that the electric field generated by a negative charge points toward the charge. Therefore, the direction of the electric field is towards the charge.
The modern model is in 3D waves unlike the Bohr which is in circularize patterns.
Answer:
(a). The initial velocity is 28.58m/s
(b). The speed when touching the ground is 33.3m/s.
Explanation:
The equations governing the position of the projectile are
where is the initial velocity.
(a).
When the projectile hits the 50m mark, ; therefore,
solving for we get:
Thus, the projectile must hit the 50m mark in 1.75s, and this condition demands from equation (1) that
which gives
(b).
The horizontal velocity remains unchanged just before the projectile touches the ground because gravity acts only along the vertical direction; therefore,
the vertical component of the velocity is
which gives a speed of
The PWC must be slowed to "slow, no wake" speed when the operator is within 50 feet of the swimmer.
"Slow, no wake" speed means the boat is at its slowest needed to keep steerage, reducing or getting rid of waves that comes out as white water trailing the boat.
Answer:
Natural gas
Explanation:
Nuclear is from splitting atoms in a nuclear power plant and doesn't emit GHG.
Hydroelectric is a clean energy which powered by water currents in turn not emitting any GHG.
Geothermal is heat captured from underneath the surface and within Earth and doesn't have GHG once the contruction of putting pipes underground is done.
Natural gas once burned emits GHG.
