Answer:
Heat is transferred from the fire through the wire by conduction.
Explanation:
Answer:
1.52s
Explanation:
Given parameters:
Acceleration = 63m/s²
Final velocity = 96m/s
Unknown:
Time taken = ?
Solution:
To solve this problem, we use one of the kinematics equation:
v = u + at
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time taken
So;
96 = 0 + 63t
t = 1.52s
The activation energy is 10 kJ and the reaction is exothermic.
Before answering this question it is necessary to know the conversion factors for temperatures.
<em>273 k = 0 ° C
</em>
To transform a temperature from Kelvin to ° C we use the following Formula
T ° C = T Kelvin - 273
<u>For 373 K</u>
373K -273 = 100 ° C
<em>373 Kelvin equals 100° C.
</em>
To transform a temperature from ° C to ° F we use the following formula:
(T° C x 9/5) + 32 = T ° F
Then:
<u>For 0 ° C
</u>
(0° C x 9/5) +32 = 32 ° F
<em>0° C equals 32 ° F.
</em>
<u>For 100° C
</u>
(100 ° C x 9/5) +32 = 212 F
<em>100 ° C equals 212 ° F.
</em>
Therefore, the correct option is the first:
373 Kelvin = 100 ° C = 212 ° F
Plants and algae use sunlight to make food. They do this with the process of photosynthesis, and they create excess oxygen as a waste product. The oxygen is vital for other living organisms to survive and perform their daily functions. Hope this helps :)
