Answer:
156,800 N
Explanation:
Given: Width = 2.0 m Length = 4.0 m Depth = 2.00 cm. Density of water = 1000 Kg/m³
To find: What is the weight of the truck?
Formula: [tex]F = m[/tex] × [tex]9.8 m/s^2[/tex]
Solution: Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s² on Earth. F is the object's weight in Newtons (N) and m is the object's mass in kilograms.
Firstly, multiply the length, width, and depth.
[tex]2.0[/tex] × [tex]4.0[/tex] × [tex]2.00[/tex] [tex]= 16[/tex]
Next, the weight of the truck is found by multiplying the density of water, the result found by multiplying the length, width, and depth, and the formula;
[tex]1000 kg/m^3[/tex] × [tex]16[/tex] × [tex]9.8m/s^2[/tex][tex]= 156,800[/tex]
Therefore, the weight of the truck is 156,800 N

A seesaw is 4.0m long with a pivot at its midpoint. A boy who weighs 400N sits at a distance of 1.5m from the pivot. His sister weighs 300N. Calculate the distance at which the girl must sit if the beam is ti be balanced
Answer:
the girl must sit 2 cm from the pivot at the opposite end of the seesaw.
Explanation:
Given;
length of the seesaw, L = 4.0 m
weight of the boy, W₁ = 400 N
position of the boy from the pivot, d₁ = 1.5 m
weight of her sister, W₂ = 300 N
First, make a sketch of this information given;
0---0.5m---------------------Δ--------------------------4m
↓<--------1.5m-------> <---------x--------->↓
400 N 300N
Apply the principle of moment about the pivot, to determine the value of x;
Sum of anticlockwise moment = sum of clockwise moment
400(1.5) = 300(x)
600 = 300x
x = 600/300
x = 2 cm
Thus, the girl must sit 2 cm from the pivot at the opposite end of the seesaw.

Compare and contrast the health benefits and the amount of physical or mental energy needed between active leisure activities and passive leisure activities
Answer:
Q...Compare and contrast the health benefits and the amount of physical or mental energy needed between active leisure activities and passive leisure activities.
A..Some active leisure activities, such as yoga and running, require a great deal of physical energy, while other activities, like playing chess, require a substantial amount of mental energy. Passive leisure activities, such as watching TV or going to the movies, require little to no physical or mental energy. Because of the exertion of physical or mental energy, active leisure activities have more health benefits than passive leisure activities.xplanation:

The current through a heater is 12 A when it is plugged into a
120 V source. What is the resistance of the heater?
A. .10Ω
B. 10Ω
C. 132Ω
D. 1440Ω
Answer:
A. 10Ω
Explanation:
the resistance of a heater with a current of 12 A and plugged to a voltage of 120 V is B. 10 Ω
Resistance: This can be defined as the opposition to the flow of current in an electric circuit.
In other to solve the problem above, make use of ohm's law
Ohm's can be represented mathematically as
V = IR................... Equation 1
Where V = Voltage, I = Current, R = Resistance
From the question,
make R the subject of the equation
R = V/I.............. Equation 2
Given: V = 120 V, I = 12 A
Substitute these values into equation 2
R = 120/12
R = 10 Ω
Hence the resistance of the heater is B. 10 Ω

help please physics !!
Answer:
Option A. 1 bar = 1 atm
Explanation:
Pressure has various units of measurement. Each unit of measurement can be converted to other units of measurement. For example:
1 atm = 1 bar
1 atm = 760 mmHg
1 atm = 760 torr
1 atm = 1×10⁵ N/m²
1 atm = 1×10⁵ Pa
With the above conversion scale we can convert from one unit to the other.
Considering the question given above, it is evident from the coversion scale illustrated above that only option A is correct.
Thus,
1 bar = 1 atm

una llamada telefonica a brasil de 4 minutos costo el mes pasado 2430 si el valor por minuto se mantiene cualto debo pagar por una llamada de 6 minutos a ese pais
Answer:
Costo = 3645
Explanation:
Dados los siguientes datos;
Costo de la llamada = 2430
Duración = 4 minutos
En primer lugar, encontraríamos el costo por minuto;
Costo por minuto, Cpm = 2430/4
Cpm = 607.5
A continuación, para encontrar el costo de 6 minutos;
Costo = 607,5 * 6
Costo = 3645

4-year-old becomes frightened of the dark and refuses to go to sleep at night. How would a psychoanalyst and a behaviorist differ in their views of how this problem developed?
Answer:
A psychoanalyst would see the 4-year-old as having an unresolved conflict where the brain judges or evaluates how good or bad the darkness is, or the usefulness of sleeping in the dark at night based on a comparison, due to the child's exploration of the world around him. A psychoanalyst might see the child's refusal to sleep at night due to the dark as a fear created for instance when the child sleeps alone without the parent. This might change if the child sleeps at night beside the parent in the dark.
While behaviorists would look at how having previous negative experiences in the dark influences a child's behavior towards staying in the dark. This fear would be reinforced with more negative experiences in the dark such as having a bad nightmare whenever the child sleeps in the dark, a feeling of hearing, or seeing strange things while in the dark. These examples would have built a behavioral pattern where the child would be conditioned to respond fearfully to being in the dark.
