Answer : When the forces are acting in the same direction of movement of the object it can be said as sum of the two individual forces will be equal to the "NET FORCE" .
Example : If two forces (2 kids pushing in the same direction to move the object big box) act on an object(big box) in the same direction, then the net force is equal to the sum of the two forces.
Answer:
1.2 °C
Step-by-step explanation:
The formula relating the heat (q) absorbed by an object, the mass (m), and the temperature change (ΔT) is
q = mCΔT Divide both sides by mC
ΔT = q/(mC)
<em>Data:
</em>
q = 15 J
m = 3.0 g
C = 4.184 J·°C⁻¹g⁻¹
<em>Calculation:
</em>
ΔT = 15/(3.0 × 4.184)
ΔT = 15/12.6
ΔT = 1.2 °C
Answer: D
Explanation: because the earth is slanted and at the north and south pole do not get that much sunlight so that makes it colder than most places on earth
Since we already know that HCl is an acid and acids have low pH values, it must have pH less than 7, so we can conclude that it has A low pH and A high pOH value.
So, the solution containing HCl must be the same.
That is :
A low pH and a high pOH
