Answer:
The magnitudes of the speed and acceleration of the Earth are approximately 66,661.217 miles per hour and 47.782 miles per square hour, respectively.
Explanation:
Given that the Earth has a circular orbit and make a revolution at constant speed around the Sun. Then, the kinematic formulas for the speed and acceleration of the planet are, respectively:
Speed
(1)
Acceleration
(2)
Where:
- Speed of the planet, measured in miles per hour.
- Acceleration of the planet, measured in miles per square hour.
- Radius of the orbit, measured in miles.
- Period of rotation, measured in hours.
If we know that and , then the magnitudes of the speed and acceleration of the planet is:
The magnitudes of the speed and acceleration of the Earth are approximately 66,661.217 miles per hour and 47.782 miles per square hour, respectively.
Answer:
The answer to your question is: 245 m
Explanation:
data
vo = 70 m/s
vf = 0 m/s
a = 10 m/s²
d = ?
Formula
vf² = vo² + 2ad
d = (vf² - vo²) / 2a
Process
d = (0² - 70²) / 2(10) substitution
d= 4900 / 20 simplify
d = 245 m
Answer:
When gametes are formed, each allele of one parent segregates randomly into the gametes, such that half of the parent's gametes carry each allele.
Since the cation (A) has a charge twice in magnitude than that of the anion (X), you can say the magnitude of the charge of the cation is 2c, while the magnitude of the charge of the anion is c.
Also remember that cations are positive ions, so the charge would be +2c, and that anions are negative ions, so the charge would be -c.
A binary ionic compound of A and X would have to have a net charge of zero. If A has a +2c charge, you would need two X anions to balance out every A cation, so the formula would be:
The simplest formula would be
.
