True

Earth’s axis slowly but continuously points in different directions in a phenomenon called <u>axial precession</u>.

Explanation:

The tilt of the earth is not constant at 23.5 degrees.  Rather the earth's axis precesses in a cycle of approximately 25,772 years. This slow precession can have an apparent effect on climate on earth, especially in conjunction with <em>Milankovitch cycles</em> like aphelion and perihelion. Due to the axial precession, the poles can be facing to or away from the sun during aphelion or perihelion. This consequently can affect the cover ice sheet and glacier in the poles due to the time of exposure to sun rays.

An arrow is shot vertically upward at a rate of 250ft/s. Use the projectile formula h=−16t2+v0t to determine at what time(s), in
SIZIF [17.4K]

Answer:

The arrow is at a height of 500 feet at time t = 2.35 seconds.

Explanation:

It is given that,

An arrow is shot vertically upward at a rate of 250 ft/s, v₀ = 250 ft/s

The projectile formula is given by :

h=-16t^2+v_ot

We need to find the time(s), in seconds, the arrow is at a height of 500 ft. So,

-16t^2+250t=500

On solving the above quadratic equation, we get the value of t as, t = 2.35 seconds

So, the arrow is at a height of 500 feet at time t = 2.35 seconds. Hence, this is the required solution.

How can we use thermal energy to our advantage?
devlian [24]

Answer:

One of the primary advantages of thermal power is that the generation costs are extremely low. No fuel is needed to generate the power, and the minimal energy needed to pump water to the Earth's surface can be taken from the total energy yield.

What controls the frequency of a wave?
sashaice [31]

Answer:

Wave frequency can be measured by counting the number of crests (high points) of waves that pass the fixed point in 1 second or some other time period. The higher the number is, the greater the frequency of the waves. ... For example, it is the distance between two adjacent crests in the transverse waves in the diagram.
