Answer:

D They have longer seasons

Explanation:

I think this because the days will be longer so that means that the seasons will change also.

Answer:

A.They have longer periods of revolution.

Explanation:

From Kepler's law, we understand that:

The planets revolve about the Sun in elliptical paths with Sun at one foci.
Equal areas is swiped in equal interval of time.
Closer the planet, faster it moves.

Thus, planets which have longer orbits that is are farther from the Sun have longer periods of revolution. This can be directly inferred from Kepler's third law.

P² ∝ a³

where, P is the period and a is the semi-major axis.

Sedimentary layers that are deposited on an angle are called?

Akimi4 [234]

Sedimentary rocks are deposited in layers as strata, forming a structure called bedding.

Bedding planes are surfaces that separate one layer from another. Bedding planes can also form when the upper part of a sediment layer is eroded away before the next episode of deposition. Strata separated by a bedding plane may have different grain sizes, grain compositions, or colors. Sometimes these other traits are better indicators of stratification as bedding planes may be very subtle.

A basketball has a mass of 601 g. Moving to the right and heading downward at an angle of 29 degree to the vertical, it hits the

olga55 [171]

Answer:

Change in momentum, $\Delta p=6.3\ kg-m/s$

Explanation:

It is given that,

Mass of the basketball, m = 601 g = 0.601 kg

The basketball makes an angle of 29 degrees to the vertical, it hits the floor with a speed, v = 6 m/s

It bounces up with the same speed, again moving to the right at an angle of 29 degree to the vertical. We need to find the change in momentum. It is given by :

$\Delta p=mv\ cos\theta-(-mv\ cos\theta)$

$\Delta p=2mv\ cos\theta$

$\Delta p=2\times 0.601\times 6\times \ cos(29)$

$\Delta p=6.3\ kg-m/s$

So, the change in momentum of the basketball is 6.3 kg-m/s. Hence, this is the required solution.
