Answer:
sir Isaac Newton is referred as the father of modern physics
Answer:
3 m/s
Explanation:
First, find the time it takes to land.
Given in the y direction:
Δy = 0.8 m
v₀ = 0 m/s
a = 10 m/s²
Find: t
Δy = v₀ t + ½ at²
0.8 m = (0 m/s) t + ½ (10 m/s²) t²
t = 0.4 s
Next, find the velocity needed to travel 1.2 m in that time.
Given in the x direction:
Δx = 1.2 m
a = 0 m/s²
t = 0.4 s
Find: v₀
Δx = v₀ t + ½ at²
1.2 m = v₀ (0.4 s) + ½ (0 m/s²) (0.4 s)²
v₀ = 3 m/s
In series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits.
And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.
Option A and D
<u>Explanation:</u>
A circuit consists of number of passive and active devices in it. And depending upon the connections between the passive devices, the flow of current and potential drop across them will be specified.
Like if the passive devices are connected parallel to each other, the current flow through each device will vary but the voltage drop will be same. Similarly, if the passive devices are connected in series, then the current flow will be constant in the devices but the potential drop will vary.
Thus, in series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits. And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.
You change the independent variable.
