Answer: B = 1.69 T
Explanation: Given that the
Electron velocity V = 7.4 × 10^5 m/s
Force F = - 2 × 10^-13 N
Charge q = -1.602 x 10-19 C.
We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation F = qvB sin θ .
Since the electron is moving perpendicular to a magnetic field,
sin θ = sin 90 = 1, therefore
- 2 × 10^-13 = - 1.602×10^-19 × 7.4×10^5B
B = -2×10^-13/1.2×10^-13
B = 1.68708T
B = 1.69 T
Vi = 0m/s
A = 99m/
Vf = 445m/s
T = 4.5s
D = ?
D = Vi(t) + 1/2(a)(t²)
D = 0m/s ( 4.5s) + 1/2(99m/s²)(4.5s)²
D = 1002 m
D = 1 x 10³ m
Answer:
what do you mean ???????????
The peak speed of Steve races in kilometer per hour is 2.423 km/h.
<h3 />
<h3>What is peak speed?</h3>
Peak speed is the maximum change in the distance traveled by an object over a period of time.
The given peak speed;
V = 67.3 cm/s
The peak speed is converted to kilometer per hour as follows;
Thus, the peak speed of Steve races in kilometer per hour is 2.423 km/h.
