Atmosphere and life were also not formed at that time. During the first period of time the temperature of Earth's atmosphere was extremely high and collisions were continuously happening between celestial bodies.

When hurled at an angle to the horizontal, a projectile can only rise to a height that is half its horizontal range. The length of a ball is represented by the equation h(t)=-16t+48t+160, where T is the launch time.

Any projectile that reaches its maximum height has zero instantaneous speed. Because gravity provides the ball a same velocity on the way up (slowing) as on the way down, the time required for the ball to travel to its highest point and return to its launch position is equal (speeding it up).

The vertex, which is a maximum (or lowest) in a parabola, can be located by solving the square (yuck!) or by using the formula x = -b/2a. By adding this x value back into the previous equation, which corresponds to the vertex's x, we may get the associated maximum height.

Answer:

approximately 1/6

Explanation:

The range of an ideal projectile depends on the initial velocity, the launch angle, and the acceleration due to gravity. The formula for the range of an ideal projectile is given by:

R = (v0^2 sin(2θ0)) / g

Where v0 is the initial velocity, θ0 is the launch angle, and g is the acceleration due to gravity.

For the moon, the acceleration due to gravity is 1.62 m/s^2, and for the earth, it is 9.8 m/s^2. The ratio of the ranges on the moon to the range on the earth can be expressed as:

rmoon/rearth = (1.62 * sin(2θ0)) / (9.8 * sin(2θ0)) = 1.62 / 9.8 = approximately 1/6

So, the range of an ideal projectile on the moon is approximately a sixth of the range of the same projectile on earth.

A capacitor is a device that stores electrical energy in an electric field by collecting electric charges on two isolated surfaces. It is a two-terminal passive electrical component. Capacitance is the effect of a capacitor.

Here,

The capacitance of a parallel plate capacitor can be calculated using the formula:

C = ε0 * εr * A / d

Where:

ε0 = 8.854 x 10⁻¹² (permittivity of free space)

εr = 3.7 (relative permittivity of paper)

A = (216 x 10⁻³ m) x (279 x 10⁻³ m) = 0.0608 m² (surface area of one plate)

d = 0.022 x 10⁻³ m (distance between the plates)

Substituting the values, we get:

C = 8.854 x 10⁻¹² x 3.7 x 0.0608 / 0.022 x 10⁻³

C = 3.03 x 10⁻ ⁹F(Farads)

2) E-Field lines encircle positive charges in circles: FALSE.

With the exception of infinity, E-Field lines begin with positive charges and end with negative charges.

3) E-field lines are oriented inward and toward electrostatic repulsion: TRUE

Negative charges attract positive charges, therefore the positive test charging will move in the direction of the negative charges as the E-field lines move along trajectory that would include a positive drug test charge.

4) E-Field vector may intersect: FALSE

If they crossed, it would imply that the electric potential may be developing variably at the exact spot, which is not conceivable because the E-Field seems to be the gradient of both the electrostatic attraction (thus they have always had the direction of the highest change of potential).

5) Positive charges have E-Field lines pointing outward: TRUE

According to the previous explanation, the E-field traces follow the path that a positive test charges would take if it were to produce the field. As a result, if a positive charge creates the field, the analysis suggests would move away from it, and the field lines would then point outward.

6) The E-field must really be weak when the E-field margins are dense: FALSE
