First write down all the known variables:
vi = 10m/s
t = 1
a = -9.8m/s^2
vf = ?
Now choose the kinematic equation to relate these variables:
vf = vi + at
vf = (10) + (-9.8)(1)
vf = 0.2 m/s
The speed of the object travelling after a second would be 0.2m/s in reality, however, it is closest to the choice A, which would suffice as the answer for your question.
Answer:36
Explanation:To analyze a series-parallel combination circuit, follow these steps: Reduce the original circuit to a single equivalent resistor, re-drawing the circuit in each step of reduction as simple series and simple parallel parts are reduced to single, equivalent resistors. Solve for total resistance.
Answer:
or 0.07163 T into the page
Explanation:
m = Mass of particle = 10 g
a = Acceleration due to gravity = -9.8j m/s²
v = Velocity of particle = 19i km/s
q = Charge of particle = 72 μC
B = Magnetic field
Here the magnetic and gravitational forces on the particle are applied in the opposite direction so,
The magnetic field is 0.07163 T into the page
