Answer:
β = 16.7°
Explanation:
The sum of forces on the x-axis are:
The sum of forces on the y-axis are:
By dividing x-axis by the y-axis equation:
Solving for β:
β = 16.7°

Answer:
The average global temperatures has increased since 1880 due to the emission of toxic gases in the atmosphere.
Explanation:
- In average the global temperature of the earth has increased by 1 degree Celsius (2 degrees Fahrenheit). It includes the combined land and ocean's temperature.
- The main reason for this increase in global temperature is the emission of gases like carbon dioxide, CFC's and other greenhouse gases.
- Human activities, industrialization, modernization etc. are majorly responsible for this increment in temperature through the centuries.
The weight of the block is (mass x gravity) = (50kg x 9.8 m/s²) = 490 N
The NET vertical force on the block is (490N down) + (600N up) = 110N up.
Acceleration = (net force) / (mass)
Acceleration = (110N up) / (50 kg)
<em>Acceleration = 2.2 m/s² up</em>
Answer:
The question implies that force of friction is 2.1E4 N
F = M v^2 / R frictional force needed to supply this centripetal force
2.1E4 = M v^2 / R
v^2 = R * 2.1E4 / M
v^2 = 120 * 2.1E4 / 2.5E3 = 1200 * 2.1 / 2.5 = 1008 m^2/s^2
v = 31.7 m/s max speed of truck (about 70 MPH)
