Answer:
W = 145.8 [N]
Explanation:
To solve this problem we must remember that weight is defined as the product of mass by gravity, in this case lunar gravity.
W = m*g
where:
m = mass = 90 [kg]
g = gravity acceleration = 1.62 [kg/m²]
W = 90*1.62
W = 145.8 [N]
Answer:
the swing on the right is more likely to break
since the vertical component of the tension of the rope has to balance the weight. ie. the resultant tension in the rope is greater
Answer:
The temperature of hot reservoir is 669.24 K.
Explanation:
It is given that,
Efficiency of gasoline engine, 
Temperature of cold reservoir, 
We need to find the temperature of hot reservoir. The efficiency of Carnot engine is given by :
So, the temperature of hot reservoir is 669.24 K. Hence, this is the required solution.
Answer:science is used to make new products
Explanation:
APEX
The Richter Scale is not commonly used anymore, except for small earthquakesrecorded locally, for which ML and Mblg are the only magnitudes that can be measured. For all other earthquakes, the moment magnitude scale is a more accurate measure of the earthquake size.
