Answer:
Silicon was touted as the revolutionary material that can do wonders in the tech industry.
Explanation:
We will apply:
Q = mcΔT; where Q is the heat, m is the mass, c is the specific heat capacity and ΔT is the temperature change.
30,000 = 390 x 3.9 x ΔT
ΔT = 19.7 °C
The temperature change is of 19.7 °C.
Answer:
638 m.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 94 m/s
Final velocity (v) = 22 m/s
Time (t) = 11 s
Distance (s) =?
We can obtain the distance travelled by using the following formula:
s = (u + v) t /2
s = (94 + 22) × 11 /2
s = 116 × 11 /2
s = 1276 /2
s = 638 m
Thus, the distance travelled is 638 m.
Answer:
(a) T1 = 938.3lb
(b) R = 665.5lb
The detail solution to this problem can be found in the attachment below.
This problem was solved by resolving the forces along the vertical and horizontal and equating to Rx and Ry respectively. Rx = 0 because the resultant is directed along the vertical.
