Explanation:

1. The mass of a substance per unit volume: Density

Higher density means the atoms are closely packed.

2. a proposed explanation for a scientific problem: Hypothesis

Before a problem is solved with an experimental or theoretical proof a hypothesis is given which is a probable solution for the problem. This hypothesis might be proved wrong at a later stage but it still works as a starting point to find a solution.

3. standard metric unit of length : Meter

The standard unit to measure the length.

4. standard metric unit of mass: Kilogram

The standard unit to measure the mass.

5. anything that has mass and occupies space: Matter

6. a quantity in an experiment that remains un-changed or constant: Control

For a snowboard jumper in the air, what force or forces will be most important for modeling the motion?
Reptile [31]

Answer: Gravitational force and drag force

Explanation:

For a snowboard jumper in the air, two forces would be acting. One in the downward direction- the gravitational pull and second in the opposite direction to the motion, the drag force due to air. If the snowboard jumper jumps in the air at a certain angle with the horizontal. The forces are written as the sum of vertical and horizontal components. Hence, for the modeling the motion, gravitational force and drag force are important,

A 2100-kg pile driver is used to drive a steel I-beam into the ground. The pile driver falls 5.00 m before coming into contact w
aliya0001 [1]

Answer:

   f = 878,080 N

Explanation:

mass of pile driver (m) = 2100 kg

distance of pile driver to steel beam (s) = 5 m

depth of steel driven (d) = 12 cm = 0.12 m

acceleration due to gravity (g0 = 9.8 m/s^{2}

calculate the average force exerted on the pile driver by the beam.

  • from work done = force x distance
  • work done = change in potential energy of the pile driver
  • equating the two equations above we have

               force x distance = m x g x (s - d)

              f x 0.12 = 2100 x 9.8 x (5- (-0.12))

              d = - 0.12 because the steel beam went down at we are taking its  

              initial position to be an origin point which is 0

              f = ( 2100 x 9.8 x (5- (-0.12)) ) ÷ 0.12

                   f = 878,080 N
