Answer:
(a) θ = 20°
(b) Time Delay = 2.84 s
Explanation:
(a)
This is the case of the projectile motion. In projectile motion, for the same launch speed, the range of a projectile is the same for the complimentary launch angles. Hence, the snowball will have the same range when launched at 70°, at an angle of:
<u>θ = 20°</u>
<u></u>
(b)
The time of flight of snowball can be found by the following formula:
where,
T = Time of flight = ?
u = launch speed = 23.3 m/s
g = acceleration due to gravity = 9.81 m/s²
For θ = 70° :
T₇₀ = 4.46 s
For θ = 20° :
T₂₀ = 1.62 s
Therefore, the time delay can be calculated as follows:
<u>Time Delay = 2.84 s</u>
Answer:
Component
Explanation:
All circuits have some basic parts, called components. One component is the power source, also called a voltage source. The power source is what pushes the electricity through the circuit.
The components of the velocity vector that represent the change in the particle's position vector will be independent of one another as long as the components of the particle's position vector are independent of one another.
Can the z component of the acceleration affect the x and y component?
- Similar to position and velocity vector components, acceleration vector components are also independent of one another.
- For example, any change in the z component of the acceleration vector would not affect the x or y components of the object's position and velocity vector.
- However, if one makes the assumption that, let's say, the particle's x position is dependent on its z position The x component of the position vector can then be connected to any change in the z component of the velocity vector.
- The x component of the position vector can be adjusted to account for any changes in the z component of the acceleration vector.

I understand that the question you are looking for is "A particle moves in three-dimensional space with a constant acceleration. Can the z component of the acceleration affect the x component of its location? Can the z component of the acceleration affect the y component of the velocity?"
Answer:
The two rays, CY and DM are diverging rays and when extended behind the mirror, they appear to intersect each other at point M'. Therefore, the properties of the images formed here are formed behind the mirror, between the pole and principal focus (f), the images are diminished and are virtual and erect.
Explanation:
<h2>Spherical Mirrors</h2>
- There are two kinds of spherical mirrors, concave and convex.
- The focal point (F) of a concave mirror is the point at which a parallel beam of light is "focussed" after reflection in the mirror. ...
- The focal length (f) and radius of curvature (R) are defined in the diagram at the right.

<span>The current from the power source will not change when the second light bulb is attached. This is because the current is kept on a single path, it will return to the power source at the same value it left the source at.</span>
