Answer: 48 m
Explanation:
Since we are dealing with constant acceleration, we can use the following equations:
(1)
(2)
Where:
is the cart’s final velocity
is the cart’s initial velocity
is the cart's acceleration
is the time
is the cart's displacement
So, firstly we have to find from (1):
(3)
(4)
Isolating from (2) and substituting (4):
(5)
(6)
Finally:
Answer:
From the following statements about mechanical waves, identify those that are true for transverse mechanical waves only, those that are true for longitudinal mechanical waves only, and those that are true for both types of waves.
Explanation:
Answer:less
Explanation:thats the answer
Answer:
In constructive interference, a crest meets a crest or a trough meets a trough, resulting in a larger crest or trough.
In destructive interference, a crest meets a trough and results in cancellation hence a smaller disturbance than either of the two interacting waves.
Answer:
4 and 6 are true
Explanation:
Let's analyze we use Gauss's law every situation presented
R1. False The sphere is insulating, so the entire charge is evenly distributed throughout the volume, but the sign of the charge does not change.
R2. False In a conductor the entire charge is on the surface, therefore the electric field inside is zero, in an insulating sphere the electric field as the charge is distributed the field is proportional to the charge inside the Gaussian surface
R.3. False in a metallic sphere the charge is on the surface, by gauss law, inside it there is no charge, or therefore there is no electric field
R4 True. The electric field is as if all the charge were at the origin and the field lines have the same direction of the radii of the sphere that are perpendicular to the surface
R5 False In a metallic sphere the entire charge is on the surface, so the field is zero inside, instead a point charge has a non-zero field
R6 True. The load is on the surface
