Answer:
In order to determine if the cathode ray consisted of charged particles, Thomson used magnets and charged plates to deflect the cathode ray. He observed that cathode rays were deflected by a magnetic field in the same manner as a wire carrying an electric current, which was known to be negatively charged.
Explanation:
According to the right-hand rule, the magnetic field causes the electrons to be refracted. Turn on the power strip to learn about the Cathode Ray (electron beam) Deflection by an Electric Field.
What is Magnetic Field?Magnetic forces can be seen in a magnetic field, an electric current, a changing electric field, or a vector field around a magnet. Magnetic compass needles and other permanent magnets align in the direction of magnetic fields like the one found on Earth. Electrically charged particles are forced to move in a circular or helical pattern by magnetic fields. The operation of electric motors is caused by this force, which is applied to electric currents in wires in a magnetic field.
The Lorentz Force, which is explained by the left-hand rule, has an impact on what happens inside the tube. In accordance with this law, an electron or other charged particle travelling in a magnetic field will be deflected by the field at a right angle to both the field's direction and the direction of the particle.

you push on box g that is next to box h, causing both boxes to slide along the floor, as shown in the figure. the reaction force to your push is
The reaction force to your push is the push of box G against you.
Newton's third law states that:
For every action, there is an equal opposite reaction.
So if an object x pulls or pushes an object y with a certain force, object y also exerts an equal and opposite force on object x.
Now, if you should push box G with a certain force, box G will exert an equal opposite force on you.
Hence, the reaction force to your push is the push of box G against you.

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.

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.

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
=> [tex]\mathsf{I=\frac{40}{230} }[/tex]
=> I = [tex]\mathsf{\frac{4}{23} }[/tex]
=> I = 0.174 A
I is the current, the computer draws when connected to a 230 V mains supply, and it's SI unit is Amperes.

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.

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.
