What do you notice about the angle of earth?
Butoxors [25]

Answer:

hi

Explanation:

Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists. ... Over the course of a year, the angle of tilt does not vary

A golf ball bounces down a flight of steel stairs, striking several steps on the way down, but never hitting the edge of a step.
frez [133]

Answer:

2.63m

Explanation:

In order to use this expression, we must calculate the values of Velocity (V0) and Velocity(Ve). The initial velocity has only a horizontal component V(0) = V(0x), the final velocity also has a horizontal component since the ball it's at a point of trajectory, V(e) = V(ef). No forces act in the horizontal direction so the momentum of the ball in this direction is conserved, hence, V(0) = V(e)

Therefore, h(e) = h(0) = 2.63m

An electron with speed of 104 m/s enters a ""forbidden"" region where an electric force tries to push it back along its path wit
dangina [55]

Answer:

The distance travelled is 151.22m and it took 0.97s

Explanation:

Well, this is an ARM problem, so we will need the following formulas

x(t)=x_{0} +v_{0} *(t-t_{0} )+0.5*a*(t-t_{0} )^{2}

v(t)=v_{0} +a*(t-t_{0} )

where x_{0} is the initial position (we can assume is zero), v_{0} is the initial speed of 104 m/s, t_{0} is the initial time (we also assume is zero), a is the acceleration of 107 m/s2, v is speed, x is position and t is time.

Now that we have the formulas, we know that when the electron stops it has no speed. Then we calculate how much time it takes to stop.

0=104m/s-107m/s^{2} *t\\t=0.97s

Finally, we calculate the distance travelled in this time

x(0.97s)=104m/s*0.97s+0.5*107m/s^{2}*(0.97s)^{2}=151.22m
