People with a good credit score usually have high salaries and their job is safe, usually in a respectable place or a company. They are known to always pay their debt on time and thus ensure that their credit score is high meaning that there is a chance that they will be given better interests or similar things when they apply for a loan again.
V=0,1 l=100 ml
m=p*V=0,8787*100=87,87g
Answer:
The specific heat capacity is 0.67
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
The amount of heat that a body receives or transmits is determined by the following expression:
Q = c * m * ΔT
Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
This expression indicates that between heat and temperature there is a direct proportional relationship.
In this case:
- Q= 100 J
- c= ?
- m= 5 g
- ΔT= Tfinal - Tinitial= 40 °C - 10 °C= 30 °C
Replacing:
100 J= c*5 g* 30°C
Solving:
c= 0.67

Answer:
Explanation:
Data:
Mass of NaCl = 4.6 g
Mass of water = 250 g
Calculations:
Mass of solution = mass of NaCl + mass of water = 4.6 g + 250 g = 254.6 g.
Answer:
Erosion.
Explanation:
It can be as small as a grain of sand or as large as a boulder. Sediment moves from one place to another through the process of erosion. Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind.
