56 Newtons bc w=F×D so if you divide by D on both side you get w/D=F
Answer: 25 m
Explanation:
The resolving power of a telescope is given by:
Diameter of the telescope = 10.0 m
Wavelength of the telescope = 550 nm = 550 ×10⁻⁹m
Thus, the resolving power of one of telescopes at the Keck Observatory is:
Also,
separation between objects = tan (3.85×10⁻⁶)° × 3.8×10⁵km = 2.5 × 10⁻²km =25 m
Answer:
The time period of the empty car will be "1.00 s".
Explanation:
The given values in the question will be:
Mass,
m = 250 kg
Loaded car's time period will be:
T = 1.08 s
Shock absorbers compression,
x = 4 cm
or,
= 0.04 m
Now,
Weight of passengers will be:
⇒
The spring constant of shock absorbers will be:
⇒
As we know,
Time period,
On substituting the values, we get
(Total mass of car as well as its passengers)
Now,
The mass of the empty car will be:
⇒
hence,
The time period of empty car will be:
⇒
or,
Answer:
= 1.46 × 10 ¹⁰ electron
Explanation:
Given that
E, Electric field = 1000N/C
D, Diameter = 29cm
r, radius = 0.145
E = kq/r²
→ q = Er²/k
q = (1000 × (0.145)² ) / (9 × 10⁹)
q = 2.34 × 10⁻⁹C
q = Ne
where e = 1.6 × 10⁻¹⁹
N = (2.34 × 10⁻⁹) / (1.6 × 10⁻¹⁹)
= 1.46 × 10¹⁰ electron
The answer would be in space because there is no matter and if there isn't matter the sound of a ringing cell phone could not be transmitted.
