Answer:
5.71428571422 m/s
Explanation:
u = Initial velocity = 20 m/s
v = Final velocity
s = Displacement
a = Acceleration
Time taken = 15-1 = 14 s
Distance traveled in 1 second =
The speed as she reaches the light at the instant it turns green is 5.71428571422 m/s
Answer:
Breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.
Explanation:
Answer:
r = 0.63 AU
Explanation:
In this question, we are interested in calculating the distance from the sun that the satellite should orbit.
From the question;
given time period of satellite is T = 0.5 year
Mathematically;
T is directy proportional to r^3/2
Hence;
T = constant * r^3/2
0.5/1 = r^1.5 / 1^1.5
( 1 is the the distance of the earth’s orbit to the sun in AU)
r = 0.63 AU
Answer:
Explanation:
Capacitance of the capacitor
C = ε₀ A / d
(8.85 x 10⁻¹² x .25² x 10⁻⁴) / 1 x 10⁻³
C = .553125 x 10⁻¹³ F
Charge = capacitance x volt
= .553125 x 10⁻¹³ x 1.5
= .8296875 x 10⁻¹³ C
no of electrons
= charge / charge on one electron
= .8296875 10⁻¹³/ 1.6 x 10⁻¹⁹
= 5.2 x 10^5
