1800 cm3 of fresh water of density 1000 km
is mixed with 2200cm of water of density
1025kg3.calculate the density of the mixture.
Answer:
the density of seawater is thousand kg
Explanation:
A 30.6 kg crate initially at rest on a horizontal floor requires a 100 N 30° with the horizontal force to set it in motion. Find the coefficient of static friction between the crate and the floor
The frictional force opposes the forward motion of the crate. The coefficient of static friction is 0.2.
Using the formula;
Fa = - Ff + mgsinθ
but Ff = μsFN and N = mgcosθ
Hence;
Fa = mgsinθ - μsmgcosθ
μsmgcosθ = mgsinθ - Fa
μk = mgsinθ - Fa/mgcosθ
μk = coefficient of static friction = ?
Fa = horizontal force = 100N
m = mass = 30.6 kg
θ = angle = 30°
g = acceleration due to gravity = 10 m/s^2
Substituting values;
μk = [(30.6 × 10) sin 30°] - 100 / (30.6 kg × 10) cos 30°
μk = 153 - 100/265
μk = 0.2

a bubble of air of volume 1cm^3 is released by a deep sea diver at a depth where the pressure is 4.0 atmospheres. assuming its temperature remains constant (T1=T2), what is its volume just before it reaches the surface where the pressure is 1.0 atmosphere?
Answer:
hope this helps!
Explanation:
Volume of the air bubble, V1=1.0cm3=1.0×10−6m3
Bubble rises to height, d=40m
Temperature at a depth of 40 m, T1=12oC=285K
Temperature at the surface of the lake, T2=35oC=308K
The pressure on the surface of the lake: P2=1atm=1×1.103×105Pa
The pressure at the depth of 40 m: P1=1atm+dρg
Where,
ρ is the density of water =103kg/m3
g is the acceleration due to gravity =9.8m/s2
∴P1=1.103×105+40×103×9.8=493300Pa
We have T1P1V1=T2P2V2
Where, V2 is the volume of the air bubble when it reaches the surface.
V2=

What is an example of a chemical change
Answer:
Hello, Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water. When exposed to water, iron becomes a mixture of several hydrated iron oxides and hydroxides.

Answer:
Sketch the situation.
b. Calculate the potential energy, the kinetic energy, and the total energy of the car as it leaves the cliff.
c. Make a graph displaying the kinetic, gravitational potential, and total energy of the car at each 10 m
increment of height as it drops
Explanation:
The potential energy of the car at that position is 10.6 x 10⁵ J.
What is meant by potential energy ?Potential energy of an object is defined as the energy acquired by the object by virtue its position.
Here,
Mass of the car, m = 1200 kg
Speed of the car, v = 29 m/s
Height of the cliff, h = 90 m
Therefore,
Potential energy of the car, PE = mgh
PE = 1200 x 9.8 x 90
PE = 10.6 x 10⁵ J
Hence,
The potential energy of the car at that position is 10.6 x 10⁵ J.

how long does it take for a pap smear to come back
by the nucleus, protons and neutrons of an atom does it contain more mass
Answer:
Virtually all the mass of an atom resides in its nucleus, according to Chemistry
Explanation:
Newton's 2nd Law of Motion says that Force is equal to the Mass of an object times its Acceleration. With that in mind how would you calculate Acceleration?
Acceleration = Mass/Force
Acceleration = Force/Mass
Momentum (p) = mass x velocity
Acceleration = Accel + er + nation - the first n
Answer: Acceleration = Force/Mass
Explanation:
F = ma
a = F/m
Acceleration = Force/Mass

Explanation:
What does auxiliary heat mean on a Honeywell thermostat.
Answer:What does aux heat mean on a Honeywell system? Short for auxiliary heat, this system is designed to heat your home up quickly instead of waiting for the cold heat pump on the exterior of your home. Unfortunately, using the auxiliary heat is significantly more expensive than using your heat pump.
Explanation:Aux on the thermostat stands for auxiliary heat. Auxiliary heat is the electric heat strip in your air handler that is supplemental heat. Emergency heat is the same thing as auxiliary heat. Auxiliary heat/ Emergency heat help the heat pump keep up when cold outside or the temperature differential on the thermostat is large.

A computer uses 40W of power. Calculate the current it draws when connected to a 230V mains supply.
Answer:
0. 174 A
Explanation:
This is similar to your other question
[tex]\boxed{\mathfrak{Power(P)=Voltage(V) \times Current(I)}}[/tex]
Voltage (V) = 230 VPower (P) = 40 W=> 40 = 230 × I

The two horizontal forces that are present as a car is pushed down the driveway are push and friction.
A force refers to that which produces or opposes motion. When force(s) is/are acting on a body, they either cause motion to occur or prevent motion from occurring. An example of a force which opposes motion is friction.
For a car being pushed along a driveway, the two possible horizontal forces that act on it are push which moves it forward and friction which resists its motion.

A. The strength of the magnet increased as the amount of current increased.
Explanation:
1. When a voltage is applied to these plates an electrical current flows charging up one plate with a positive charge with respect to the supply voltage and the other plate with an equal and opposite negative charge.
If the capacitors are connected by a conductor they must have equal potentials. If their charges are not +/- Q there will be a potential difference and charges will flow until they are +/- .
2. Based upon the results of the experiment which is graphed, an increase in current increases the number of paperclips picked up. The increase in current produced a stronger magnetic field from the electromagnet created. The ability to pick up paperclips testifies to the strength of the magnet and this strength is because of the current emitted to the coils which in turn magnetizes the nail
