The circulatory system breaks down food and gets / absorbs nutrients. The muscular system works to get nutrients to the rest of the body. The nervous system basically controls the digestive system and sends information to the brain.
I'm pretty sure I'm right, but please correct me if I'm wrong! :)
The net force acting on the car is
3 × 10^3
Newtons.
Force is defined as the product of the mass of the body and its aaceleration,
⇒ F = ma
Substituting the above given values we get,
F =(1500kg) (2.0 m/s^2) = 3000N = 3 × 10^3N .
11.54 minutes
Explanation:
The decay rate equation is given by

where
is the half-life. We can rewrite this as

Taking the natural logarithm of both sides, we get

Solving for
,



<h3><u>Answer;</u></h3>
the one with the highest specific heat
<h3><u>Explanation;</u></h3>
- The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
- The specific heat of water is 1 calorie/gram °C or 4.186 joule/gram °C which is higher than any other common substance.
- <em><u>A metal with the highest specific heat will cause the greatest increase in temperature of water in a calorimeter because the metal would hold more heat, and then transfer the greater quantity of heat to the water.</u></em>
Answer:
Distance covered by Joe, d = 5 km
Explanation:
It is given that,
Speed of Joe, v = 20 km/hour
Time taken by Joe, t = 15 minutes = 0.25 h
We need to find the distance he is covering. It can be calculated using definition of speed as :
d = 5 km
So, Joe covers a distance of 5 km. Hence, this is the required solution.
