Answer:
Decreases/Reduces
Explanation:
Fill in the blank:
Consider the equation Work = Force X Distance.
<em>If a machine increases the distance over which a force is exerted, the force
</em>
<em>required to do a given amount of work</em> .........
If the work is a constant value, then by isolating force from the equation, we get:
Force = Work / Distance
By increasing the value of the Distance, then the quotient Work. Distance diminishes, and therefore the required force decreases (diminishes, reduces)
Answer: Decreases/Reduces
Answer:
yes it was a constant speed and the car traveled 10 meters in 20 seconds.
Explanation:
TRUE.
Taste and smell senses are separate senses with their own receptor organs yet they are intimately entwined. Tastants, chemicals in foods are detected by taste buds which consist of special sensory cells.. When stimulated, these cells send signals to specific areas of the brain which then makes us conscious of the perception of taste. Also specialized cells in the nose pick up odorants, airborne odor molecules. Odorants stimulate receptor proteins found on hairlike cilia at the tips of the sensory cells, a process that initiates a neural response.
Answer:
10.21°C
Explanation:
From the question,we are given;
- Quantity of heat = 32,000 Joules
- Mass of water = 750 g
- Specific heat capacity of water = 4.18 J/g°C
We are required to calculate the change in temperature;
- We need to know that quantity of heat is calculated by multiplying mass by specific heat then by change in temperature.
- That is;
Q = m × c × ΔT
Rearranging the formula;
ΔT = (Q ÷ (m × c))
= 32,000 J ÷ (750× 4.18 J/g°C)
= 10.21°C
Therefore, the change in temperature is 10.21°C
