B) Moving with zero acceleration.
Explanation:
Acceleration is defined as the rate of change of the velocity per unit time:
In a velocity-time graph, this ratio corresponds to the slope of the curve. In fact:
(change in velocity) corresponds to the increase in the y-axis
(change in time) corresponds to the increase in the x-axis
So, acceleration corresponds to the slope of the curve in a velocity-time graph. For cart C, the slope is zero, therefore the acceleration is also zero.
Asexual propagation involves taking a part of one parent plant and causing it to regenerate itself into a new plant. The resulting new plant is genetically identical its parent. Asexual propagation involves the vegetative parts of a plant: stems, roots, or leaves.
The most common method for asexual propagation is from cuttings. A cutting is any detached plant part which, under favorable conditions for regeneration of missing parts, will produce a new plant identical to the parent plant.
Hope that help:)
Question: A charge of 0.50 C moves horizontally in a magnetic field of 1.0 T with a speed of 4.0 x 10^⁻1 m/s. The force experienced by the charge is 7.0 N. What is the angle between the charge direction and the magnetic field?
Answer:
Θ = 6.56°
Explanation:
From the question,
Using
F = BvqsinΘ................... Equation 1
Where F = force experienced by the charge, B = magnetic field, q = Charge, Θ = angle between the charge abd the magnetic field, v = velocity.
Make Θ the subject of the equation
Θ =sin⁻¹ (Bvq/F)............... Equation 2
Given: v = 4.0×10⁻¹ m/s, B = 1.0 T, q = 0.50 C, F = 7.0 N
Θ = sin⁻¹(1×0.5×4×10⁻¹/7)
Θ = sin⁻¹(0.114)
Θ = 6.56°
