What is the magnitude of the force F on the 1.0 nC charge in the figure ?
Answers
The magnitude of the force F on the 1.0 nC charge 3.11N.
What is force?
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
In this problem, the 2.0 nC charges both act forces of equal magnitude on the 1.0 nC charge. Since there x-components are equal but opposite, they cancel out and only the y-components remain and add up. This can be used then to calculate for the magnitude of the total electrostatic force.
F = 2 * q1 * q2 / 4 / pi / eps_0 / r^2 * sqrt(3) / 2
F = 2 * 1.0e-9 * 2.0e-9 / 4 / pi / 8.854e-12 / (1.0e-2)^2 * sqrt(3) / 2
F = 3.11N

KE=450
Assuming no air resistance....
Final answer:
The kinetic energy of a 1.0 kg ball thrown with an initial velocity of 30 m/s is calculated using the formula KE = 1/2 mv^2, resulting in an energy of 450 Joules.
Explanation:
The question you've asked pertains to calculating the kinetic energy of a ball thrown into the air. To find the kinetic energy (KE) of a 1.0 kg ball thrown with an initial velocity of 30 m/s, you can use the formula KE = ½ mv², where m is the mass of the ball and v is the velocity. Plugging in the values, you get KE = ½ × 1.0 kg × (30 m/s)² = 0.5 × 1.0 × 900 = 450 J. Therefore, the kinetic energy of the ball is 450 Joules.

D. Temperature: K
Answers
Answer:
C. Length: km
Explanation:
Let's analyze each option:
A. Mass: in the SI system, mass is measured in kilograms (kg), so this matching is correct.
B. Time: in the SI system, time is measured in seconds (s), so this matching is correct.
C. Length: in the SI system, length is measured in meters (m). The kilometer, instead, is a multiple of the meter (). Therefore, this matching is not correct.
D. Temperature: in the SI system, temperature is measured in Kelving (K), so this matching is correct.
