Answer:
2 and 3
Explanation:
because that's how kinetic and potential energy work
Answer:
F = 2553.6 N
Explanation:
v² = u² + 2as
0² = 16² + 2a4.0
a = -32 m/s²
F = ma = 79.8(32) = 2553.6 N
Hello!
Recall for resistors in parallel:

We can begin by calculating the total resistance:

Now, we can calculate the current using Ohm's Law:

V = Voltage of battery (V)
i = Current (A)
R = Resistance (Ω)
Plug in the given voltage and the total resistance we solved for.

The integral of acceleration is velocity. The area under the curve is an integral. You can see the relation here. So just take the area under those time intervals. I’m assuming 1.7 is where it crosses the x-axis
For the first interval:
Base = 1.7
Height = -2
[1.7*(-2)]/2 = -1.7 cm/s
For the second interval:
There are two triangles and a rectangle here.
Base #1 = 0.3
Height #1 = 1
Base #2 = 1
Height #2 = 1
Length = 3
Width = 1
Apply the area formulas to get an answer of 3.65 cm/s
Given :
Potential difference, V = 300 V.
Magnetic Field, B = 0.001 T.
To Find :
The magnitude of the magnetic force on the electron.
Solution :
We know, for perpendicular orientation, force is given by :

Hence, this is the required solution.
