Answer:
3360 N
Explanation:
In a first-class lever, the effort force and load force are on opposite sides of the fulcrum.
The lever is 5 m long. The load force is 1.50 m from the fulcrum, so the effort force must be 3.50 m from the fulcrum.
The torques are equal:
Fr = Fr
(1440 N) (3.5 m) = F (1.5 m)
F = 3360 N
Answer: i know that ice is denser than water because of the reason why ice is expanding:air. ice has tiny air packets inside that make it bigger than the original state(the state which a substance is at at room temperature.
Explanation:
Iron is an element that has been known in its pure form for at least 5,000 years. The name "iron" comes from the...
The element symbol for iron is Fe, which comes from the Latin word for iron, "ferrum."
Iron is one of the most plentiful elements. It comprises about 5.6 percent of the Earth's crust and almost all of its core
Iron is a transition metal.
Animals and plants require iron. Plants use iron in chlorophyll, the pigment used in photosynthesis. Humans use iron in hemoglobin molecules in blood to allow for the transport of oxygen to tissues throughout the body.
The weight of an object is the
force with which it is attracted to earth. The gravity of an object or body of
an object is high on earth than at the atmosphere. It has an average of
gravitational constant equal to 9.8066 or 9.8 meters per second. In truth, the acceleration
of the object depend upon its location, the latitude and altitude, on
earth.

Answer:
The answer is 7.52 m/s².
Explanation:
To determine acceleration, N = Ma×g ÷ cos Ф
N sin Ф = ma
a = g Tan Ф m/s²
g = 9.8 m/s² and Ф = 37.5° ( angle for the velocity and gravitational force)
so, a = 9.8 × tan (37.5°)
Acceleration has to be determined in order to get the final answer.
a = 7.5198 m/s²
