She misses. She should have accelerated faster in order to get to her target.
<span>Formula-
E = hc/ {wavelength}
Given in quation-wavelength=12.4 cm
We know the value of h and c.
h=6.626 * 10^-34 Js
c= 2.997 * 10^8 m/s
wavelength=12.4 cm converted to 0.124 m
E = [ 6.626 * 10^-34 Js * 2.997 * 10^8 m/s ] / 0.124 m
E = 1.60 * 10^-24 J
1.60 * 10^-24 J of energy of exactly one photon of this microwave radiation have.</span>
Answer:
Explanation:
Pascal's law states that when there is an increase in pressure at any point in a confined fluid, the pressure is equally distributed at every other point in the container.
The formulas that relate to this are given below:
P1 = P2 (since the pressures are equal throughout).
P2 is the pressure transmitted in the hydraulic system
N.B : P= Force/ Area
Therefore we have
F1/A1 = P2
F1= the force exerted by the driver = 100N
P2= 100/A1 N/m² or 100/A1 pa or 100/(101325× A1) atm
Answer:
D. 48.985 N
Explanation:
Newton's second law states that:
which means that the net force acting on an object is equal to the product between the object's mass and its acceleration.
The equation of the forces for the briefcase in the elevator therefore is given by:
where
N is the normal reaction exerted on the briefcase
(mg) is the weight of the briefcase, with
m = 4.5 kg being its mass
g = 9.8 m/s^2 is the acceleration of gravity
a = 1.10 m/s^2 is the acceleration
Here we chose upward as positive direction.
Solving for N, we find the normal force:
So the closest answer is
D. 48.985 N
D. descriptive because it makes more sense to me then all the others.
