<u>Answer</u>
46,200 J
The energy of given out when a substance is losing heat is given by:
H = mcΔθ
Where m is the mass of the substance,
c is the specific heat capacity of the substance and
Δθ is the temperature change.
H = 0.50 × 22 4200
= 46,200 Joules.
Answer:
113.53 g
Explanation:
Please see attached photo for explanation.
In the attached photo, M is the mass of the meter stick.
The value of M can be obtained as shown below:
Clockwise moment = M × 10.5
Anticlockwise moment = 65.5 × 18.2
Anticlockwise moment = Clockwise moment
65.5 × 18.2 = M × 10.5
1192.1 = M × 10.5
Divide both side by 10.5
M = 1192.1 / 10.5
M = 113.53 g
Thus, the mass of the meter stick is 113.53 g

Wire rope guardrails are supposed to be capable of withstanding a force of 200 pounds without failure, it must not deflect under pressure to less than 39 inches above the walking surface, and it must be at least a quarter inch in thickness to prevent cuts when installing around buildings. To install the metal guardrail safely, you must use a sufficient amount of clips on the wire to ensure that it will not snap under the pressure and to ensure that it is safe to walk on or use as a support.
