Answer:
P = 23.32 W
Explanation:
In series
equivalent Resistance
R(eq)=R+R=2R
In parallel equivalent resistance
R(eq) = R*R/(R+R) =R/2
since.
power
P=V² / R
in series
⇒V = √(P*R)
=√(5.83*2R
)
=√(11.66R)
in parallel
P = V² / R(eq)
=(√(11.66R)²) / (R/2)
P=11.66 * R * 2/R
P = 23.32 W
There would be a high amount of dead matter
Answer:
12 m/s
Explanation:
English Translation
At what maximum speed is the cyclist traveling for a short time if he has a maximum power of 420W and at this speed he must overcome the resistance 35N.
The Power, P, expended by a moving body with velocity, v, moving against a resistive force of F is given as
P = Fv
P = 420 W
F = 35 N
v = ?
420 = 35v
v = (420/35) = 12 m/s
In Polish/Po polsku
Moc P, wydana przez poruszające się ciało z prędkością v, poruszająca się przeciw sile oporu F, jest podana jako
P = Fv
P = 420 W
F = 35 N
v = ?
420 = 35v
v = (420/35) = 12 m/s

Answer:
This distance is measured from the center of the earth r = 3.4 10⁸ m
Explanation:
The equation for gravitational attraction force is
F = G m1 m2 / r²
Where g is the universal gravitation constant, m are the masses of the body and r is the distance between them, remember that this force is always attractive
Let's write the sum of force on the ship and place the condition that is balanced
F1 -F2 = 0
F1 = F2
Let's write this equation for our case
G m Me / r² = G m Mm / (r'.)²
The distance r is measured from the center of the earth and the distance r' is measured from the center of the moon,
r' = 3.85 10⁸ m
Let's simplify and calculate the distance
Me / r² = Mm / / (3.85 108- r)²
Me / Mm (3.85 108- r)² = r²
√ 81.4 (3.85 108 -r) = r
√ 81.4 3.85 108 = r (1 + √ 81.4)
34.74 108 = r (10.02)
r = 34.74 10⁸ / 10.2
r = 3.4 10⁸ m
This distance is measured from the center of the earth
