Answer:
The factors in the physical environment that are important to health include harmful substances, such as air pollution or proximity to toxic sites the focus of classic environmental epidemiology access to various health-related resources e.g. healthy or unhealthy foods, recreational resources, medical care.
R = V/I = 9 / 0.3
R = <span>30 ohms.</span>
Answer
given,
Pressure on the top wing = 265 m/s
speed of underneath wings = 234 m/s
mass of the airplane = 7.2 × 10³ kg
density of air = 1.29 kg/m³
using Bernoulli's equation
Applying newtons second law
2 Δ P x A - mg = 0
A = 3.53 m²
Answer:
Gravity
Explanation:
When the ball is falling to the ground, it is already detached from the table, so the table does not exert any force on it.
Gravity is always present, therefore it is acting on the ball (acting downward), so it must be included into the free-body diagram. Apart from that, there are no other forces acting on the ball (if we neglect air resistance, which is negligible, and it is not mentioned in the options given), therefore the only force which has to be included in the diagram is gravity.
Explanation:
F = k |q1| |q2| / r^2
k = 9 * 10^9
q1 = - 2.5 C
q2 = 2 C
r = 100
r^2 = (10^2)^2 = 10^4
F = (9*10^9) * ( 2.5 ) ( 2) / ( 100)^2
F = 45* 10^9 / 10^4
F = 45 * 10^9 * 10 ^ -4 = 45 * 10^5 N
F = 45 * 10 ^ 5 N
