Total distance between Sally's house and mall = 10 kilometers
Distance covered during half way drive = Kilometers
Now, she goes back to her home.
Distance covered going back home = Kilometers
Now, she drives from home to mall.
Distance covered from Sally's home to mall = 10 kilometers
Hence, the total distance Sally traveled = 5 + 5 + 10
Total distance Sally traveled = 20 kilometers
Hence, the answer is 20 kilometers
Answer:
All matter contained electrons
Explanation:
The discovery and characterization of cathode ray suggested that it was a subatomic particle and cathode ray ( electron) was the first discovered. It immensely became the strong explanatory tool for chemical bond. This can be attributed to the the ease with which electron move from one atom to the other.
Answer:
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
you can find it using the equation: potential energy=mass*gravitational acceleration*height.
energy=50kg*9.8N/kg*40m=19600Nm=19600J or 19.6kJ
Sometimes they use 10 instead of 9.8 for the g constant.

The correct option from given choices is 2, that is 0.24 m
We can find this by using the following formula;
ln A = ln Ao - kt
Ao = 0.30
k = 0.080 min⁻¹
t = 2..6 min
<span>ln A = ln 0.30 - (0.080 min</span>⁻¹<span>) (2.6 min) </span>
<span>ln A = -1.412 </span>
<span>A = 0.24 m</span>
