Answer:
When a disaster is declared, the Federal government, led by the Federal Emergency Management Agency (FEMA), responds at the request of, and in support of, States, Tribes, Territories, and Insular Areas and local jurisdictions impacted by a disaster.
Explanation:
Answer:
E = F/q
Explanation:
Electric Field (E) : Electric Field (E) of an electrostatic field is defined as the force (F), per unit test charge (q) which it exert at that point. Its direction is that of the force exerted on a positive charge. The S.I unit of Electric field is Newtons per coulombs. (N/C).
Electric Field (E) can be expressed mathematically as,
E = F/q
Where F = Electrostatic force (Newton), q = charge (coulombs), E = Electric field.
A. Starts slowly and then accelerates.
The models are used to represent what you are studying in this case would be a planet. A model of Saturn and its rings and the moons surrounding it would be fantastic to look at when you have no way of going there
Answer:
4 seconds
Explanation:
Start with this observation: the distance traveled by car A, plus the distance traveled by car B, plus the original 15 meter gap, equals the 55 meter separation at time t.
dA + dB + 15 = 55
You're given the equation for distance traveled at constant acceleration when the initial velocity is 0:
d = 0.5at²
Given that the acceleration of car A is 2 m/s² and the acceleration of car B is 3 m/s², all you have to do is plug in the expressions and variables and solve for t.
0.5 (2) t² + 0.5 (3) t² + 15 = 55
t² + 1.5 t² = 40
2.5 t² = 40
t² = 16
t = 4
