Answer:
Move further apart
Explanation:
The negative charge on the rod repels the electrons on the cap thus they concentrate at the leaves causing an increase in the amount of charge at the leaves. Since like charges repel, the two leaves of the electroscope move further apart.
The y component of the vector is 37.7 N and the angle between the vectors is 26.2⁰.
<h3>Y-component of the vector</h3>
The y component of the vector will be determined from the resultant vector and the x component of the vector.
R² = Y² + X²
Y² = R² - X²
Where;
- Y is the y-component of the vector
- X is the x component of the vector
- R is the resultant vector
Y² = 85.2² - 76.4²
Y² = 1,422.08
Y = √1,422.08
Y = 37.7 N
<h3>Angle between the vectors</h3>
θ = arc tan (Y/X)
θ = arc tan (37.7/76.4)
θ = 26.2⁰
Thus, the y component of the vector is 37.7 N and the angle between the vectors is 26.2⁰.

To gather light from a far-off star, a concave mirror with a radius of curvature of 1.0 m is utilized. Most likely 0.25 meters separate the mirror from the star's picture.
A concave mirror is a kind of spherical mirror in which the reflecting surface is the inside radius of curvature of the sphere, or in other words, the reflecting surface appears to be far from the incident light source. Is called concave mirror.
The reciprocal of the curvature is known as the radius of curvature, or R. It is equal to the circumference of the circular arc that, at that location, most closely resembles the curve. The circle's radius that best matches a normal section is known as the radius of curvature for surfaces.

Answer:
A convex mirror is a diverging mirror (f is negative) and forms only one type of image. It is a case 3 image—one that is upright and smaller than the object, just as for diverging lenses.
Explanation:
hope this helps have a good night :)
Because the less dense magma is lighter so it floats to the top.
