It depends on the environment around you ... the number and size of
the masses around you, and your distance from their center of mass.
If you happen to be on the surface of the Earth, then
g = 9.8 m/s²
or
g = 9.8 newton/kilogram .
It's different on other planets. Be sure to look it up
before you leave, so you'll know what to expect.
Answer:
the length of the Nichrome wire is <em>59.88 m</em>
<em></em>
Explanation:
The resistance of a wire is determined by:
P = V² / R or R = V² / P
where
- V is the voltage
- R is the resistance
- P is the power
We also know that
R = PL / A
where
- A is the area and it is equal to πr²
- P = 3.20 × 10² W
Therefore, the length of the Nichrome wire is
L = RA / ρ
L = (V²/P)(πr²) / ρ
L = V²πr² / ρ P
L = (110 V)²(π)(7.1 × 10⁻⁴ m)² / (3.2 × 10² W)(100 × 10⁻⁸ Ω·m)
<em>L = 59.88 m</em>
Answer:
Explanation:
Let density of water be ρ .
During flow , volume of water flowing per second is constant
loss of P. E per unit volume = ρ gh , 83.5 % is lost
Gain of K E per unit volume = 1/2 ρ v²
83.5 % of mgh = ρ 1/2 ρ v²
1/2 ρ v² = .835 x 9.8
v² = 2 x .835 x 9.8
= 16.366
v = 4.04 m /s
I read it’s a unit of energy
The time interval in which the larger force act is 1.1 seconds.
<h3>What is impulse?</h3>
The impulse produced by an object is determined from the product of force and time of force of the object.
The impulse experienced by an object is the product of mass and velocity of the object or simply the impulse experienced by object is equal to change in the momentum of an object.
J = Ft
where;
- F is the applied force
- t is the time of force acting
The magnitude of the force that produce impulse of 3 Ns for 3.2 seconds is calculated as;
F = J/t
F = (3 Ns) / (3.2 s)
F = 0.94 N
The magnitude of the force that is three times larger is calculated as;
F₂ = 3 x 0.94 N
F₂ = 2.82 N
The time interval of the larger force is calculated as;
t₂ = J/F₂
t₂ = 3 / 2.82
t₂ = 1.1 seconds
Thus, the impulse experienced by an object is a function of force and time of force action.
