Answer:
In our project, we have a class one lever that is hit by a pulley basket, thus letting a ball roll down.
Explanation:
Answer:
12.17 m/s²
Explanation:
The formula of period of a simple pendulum is given as,
T = 2π√(L/g)........................ Equation 1
Where T = period of the simple pendulum, L = length of the simple pendulum, g = acceleration due to gravity of the planet. π = pie
making g the subject of the equation,
g = 4π²L/T²................... Equation 2
Given: T = 1.8 s, l = 1.00 m
Constant: π = 3.14
Substitute into equation 2
g = (4×3.14²×1)/1.8²
g = 12.17 m/s²
Hence the acceleration due to gravity of the planet = 12.17 m/s²
In the Newtonian theory of gravitation, the effects of gravity are always attractive, and the resulting force is calculated with respect to the center of gravity of both objects. The law of universal gravitation formulated by Isaac Newton postulates that the force exerted by a point particle with mass M on another with mass m is directly proportional to the product of the masses (and the Universal Gravitation Constant), and inversely proportional to the square of the distance (r) that separates them:
Therefore the correct answer is 2.

Answer:
the equivalent temperature in kelvins of 30.0 degrees Roemer is 323 K
Explanation:
The computation of the equivalent temperature is as follows:
The freezing point of water is 0 degrees
As in the Roemer scale, o degrees means 0.5 degrees Roemer
Therefore
°C = ({Roemer} - 0.5 ) × 100 ÷ 59.5
As the boiling point is 100°C and the boiling point of 60.0 degrees would be obtained from the equation shown above
Now
If {° Roemer} = 30°
{°C} = (30 - 0.5) × 100 ÷ 59.5
= 49.57°C
So,
= 49.57°C + 273 K
= 322.57 K
= 323 K
Hence, the equivalent temperature in kelvins of 30.0 degrees Roemer is 323 K
