Answer:
D
Explanation:
Insulator is like rubber, it cant physically hold heat well
Answer:2.517 J/K
Explanation:
Given
Reservoir 1 Temperature
Reservoir 2 Temperature
Let Q is the amount of heat Flows i.e.
thus change in Entropy is given by
Answer:
emf = 11.667 V
Explanation:
Given: charge q = 0.060 C, electric potential energy E =0.70 J,
Solution :
by definition 1 volt = 1 joule per coulomb
so Voltage = emf = E/C
emf = 0.70 J / 0.060 C
emf = 11.667 V
Answer:
D. To ensure common resources are not overused
Explanation:
- The article of the antarctic treaty VII provides that all the consultative parties have a right to designate the observers and to undertake the inspection as of the protocol 14 of that provides the protection of the environment and to safeguard the ecological system.
- Since 1963, about 9 inspections have been conducted by the teams by visiting the stations, facilities, the vessels, and the protected areas across a wide area of East Antarctica, The most recent Antarctica expedition treaty inspection was done in Dec 2016.
Answer:
Option C. 1.2 m
Explanation:
The following data were obtained from the question:
horizontal velocity (u) = 2.08 m/s
Horizontal distance (s) = 0.96 m
Height (h) of the table =?
Next, we shall determine the time taken for the lab cart to get to the ground. This can be obtained as follow:
horizontal velocity (u) = 2.08 m/s
Horizontal distance (s) = 0.96 m
Time (t) =?
s = ut
0.96 = 2.08 × t
Divide both side by 2.08
t = 0.96 / 2.08
t = 0.5 s
Finally, we shall determine the height of the table as illustrated below:
Time (t) = 0.5 s
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) of the table =?
h = ½gt²
h = ½× 9.8 × 0.5²
h = 4.9 × 0.25
h = 1.2 m
Thus, the height of the table is 1.2 m
