Because the net force must be zero, we conclude that the magnitude of the force is 1500 newtons, and the direction is in the positive axis.
What is the magnitude and direction of the third force?
By Newton's laws, we know that if the net force applied to an object is different than zero, then the object is accelerated.
In this case, we know that the object moves with constant velocity, so there is no acceleration, meaning that the net force is equal to zero.
Then we must have:
F1 + F2 + F3 = 0N
Replacing F1 and F2 we get:
-3000 N + 1500N + F3 = 0
F3 = 3000N - 1500 N = 1500N
Then the magnitude of the force is 1500 newtons, and the direction is in the positive axis.

why didn't the geologists include dates in the notes for the sedimentary rock layers?
Answer:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

a. How far does a 100-newton force have to move to do 1,000 joules

b. An electric hoist does 500 joules of work lifting a crate 2 meters. How
much force does the hoist use?
c. An athlete does one push-up. In the process, she moves half of her body
weight, 250 newtons, a distance of 20 centimeters. This distance is the
distance her center of gravity moves when she fully extends her arms. How
much work did she do after one push-up?
d. You decide to push on a brick wall with all your might for 5 minutes. You
push so hard that you begin to sweat. However, the wall does not move. If
you end up pushing with a force of 500 newtons, how much work did you
do?
Work done by a force is given as the product of force and the distance moved by the force.
What is work done?Work done is the product of force and the distance moved by the the force.
Work done = Force × distanceThus, distance required by the 100 N force is given as:
Distance = work done/forceDistance = 1000/100 = 10 m
Distance to be moved is 10 m.
Force applied = work done/ distance
Force applied by the hoist = 500/2
Force applied by the hoist = 250 N
Distance moved in one push-up = 25 cm = 0.25 m
Work done by the athlete after one push-up = 250 × 0.25 m
Work done by the athlete = 62.5 J
Distance moved by the force = 0 m
Work done = 500 × 0 = 0 N
Therefore, for work to be done, force has to move a distance.

Determino la masa en gramos y kilogramos de 1500 cm3 de alcohol etílico, cuya densidad es aproximadamente 790.0 Kg/m3. Tomar en cuenta que: Densidad (ρ) = masa (m)/volumen(v).
Para calcular el contenido en gramos de una bebida alcohólica basta con multiplicar los grados de la misma por la densidad del alcohol (0,8). El contenido de alcohol de una bebida depende de la concentración de alcohol y del volumen contenido.
The mass in grams and in kilograms of ethyl alcohol respectively is: a) 1185.0 g and b) 1185 kg
What is density?Density is an intensive property of matter. It represents the relationship between the mass and the volume of a body or substance. Its units are in the International System kg/m3, kg/L, g/ml, g/cm3, among others.
The density formula is:Density = m/V
The mass is obtained by clearing this equation
m=Density *Volume
