This heats up when an electric current passes through it, and produces light as a result. The resistance of a lamp increases as the temperature of its filament increases. The current flowing through a filament lamp is not directly proportional to the voltage across it.
Answer:
250s
Explanation:
Given parameters:
Mass = 50kg
Speed = 10m/s
Force = 2N
Unknown:
Time the force was acting = ?
Solution:
To solve this problem, we use the equation of motion from the second law of Newton:
Ft = mV
F is the force
t is the time taken
m is the mass
V is the velocity
2 x t = 50 x 10
t = 250s
A question you can gather from this experiment is figuring out the distance traveled by the car, and how far it went. A simple solve of X equation could be used.
Answer:
42Amp

Answer:
y = 2.76 [m]
Explanation:
We can find the distance of the fall of the apple using the following kinematic equation, we have to emphasize that this is a typical problem of free fall, so the initial speed is zero, then we give the initial data.
t = time = 0,75[s]
g = gravity = 9.81[m/s^2]
v0 = 0
![y = v_{0}*t+0.5*g*t^{2}\\ y=0.5*(9.81)*(0.75)^{2}\\y= 2.76[m]](https://tex.z-dn.net/?f=y%20%3D%20v_%7B0%7D%2At%2B0.5%2Ag%2At%5E%7B2%7D%5C%5C%20y%3D0.5%2A%289.81%29%2A%280.75%29%5E%7B2%7D%5C%5Cy%3D%202.76%5Bm%5D)
