Voltmeters are typically connected in parallel because they have high resistance, while ammeters are typically connected in series to measure current since they have low resistance and the voltage drop would be minimal.
How to read ammeter reading?Ammeter resistance is typically in the range of 0.5 ohm.However, when we connect as indicated, 10 ohm and 0.5 ohm are in parallel, resulting in a 40 amp current in the ammeter and a 2 amp current in the 10 ohm resistor. As a result, the ammeter will read 40 amp even if only 2 amp of current is flowing through the 10 ohm resistance.An ammeter is a device used to gauge the current flowing through a circuit. Amperes are units used to measure electric currents, therefore the name. The ammeter is connected in series with the circuit being used to measure the current for direct measurement.For more information on ammeter kindly visit to

A 5 kg ball is sitting on top of a hill. It has a Potential Energy of 6000J. What is the height of the ball?
Answer:
h = 122.44 m
Explanation:
Given that,
Mass of a ball, m = 5 kg
Potential energy at the top of the hill, E = 6000 J
We need to find the height of the hill. The formula for the potential energy is given by :
[tex]P=mgh\\\\h=\dfrac{P}{mg}\\\\h=\dfrac{6000}{5\times 9.8}\\\\h=122.44\ m[/tex]
So, the height is 122.44 m.

A 20-gram bullet traveling at 250 m/s strikes a block of wood that weighs 2 kg. With what velocity will the block and bullet move after the collision? [convert g to kg]
Answer:
the velocity of the bullet-wood system after the collision is 2.48 m/s
Explanation:
Given;
mass of the bullet, m₀ = 20 g = 0.02 kg
velocity of the bullet, v₀ = 250 m/s
mass of the wood, m₁ = 2 kg
velocity of the wood, v₁ = 0
Let the velocity of the bullet-wood system after collision = v
Apply the principle of conservation of linear momentum to calculate the final velocity of the system;
Initial momentum = final momentum
m₀v₀ + m₁v₁ = v(m₀ + m₁)
0.02 x 250 + 2 x 0 = v(2 + 0.02)
5 + 0 = v(2.02)
5 = 2.02v
v = 5/2.02
v = 2.48 m/s
Therefore, the velocity of the bullet-wood system after the collision is 2.48 m/s

Describe how Alfred Wegener and Harry Hess contributed to the theory of Plate Tectonics.
8th Science
Answer:Dr. Hess' most significant contribution to the plate tectonic theory began in 1945 when he was the commander of the U.S.S. ... In the paper Hess described how hot magma would rise from under the crust at the Great Global Rift. When the magma cooled, it would expand and push the tectonic plates apart.
Explanation:
Explanation:
Alfred Wegener produced evidence in 1912 that the continents are in motion, but because he could not explain what forces could move them, geologists rejected his ideas. Almost 50 years later Harry Hess confirmed Wegener's ideas by using the evidence of seafloor spreading to explain what moved continents.
Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of "continental drift." Wegener proposed that the continents plowed through the crust of ocean basins, which would explain why the outlines of many coastlines (like South America and Africa) look like they fit together like a puzzle.
A car drives for 50 seconds and travels 2 meters what is its velocity

In the early universe and now, stars most likely formed from which of the following?
Group of answer choices
Nebulas
Planets
Comets
Asteroids
Answer:
Nebulas
Explanation:
Nebulae are made of dust and gases—mostly hydrogen and helium. ... Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.

A 5 kg ball is sitting on top of a hill. It has a Potential Energy of 6000J. What is the height of the ball?
Explanation:
mass=5 kg
potential energy=6000j
height=?
Now
potential energy =m.g.h

or 6000=49h
or 6000÷49=h
or h= 122.45m
What net force would be required for a 50.5 kg wolf to accelerate at 5.0 m/s^2
Answer:
[tex]\boxed {\boxed {\sf 252.5 \ Newtons }}[/tex]
Explanation:
Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.
[tex]F=m*a[/tex]
The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:
[tex]m= 50.5 \ kg[/tex][tex]a= 5.0 \ m/s^2[/tex]Substitute the values into the formula.
[tex]F= 50.5 \ kg * 5.0 \ m/s^2[/tex]
Multiply.
[tex]F=252.5 \ kg*m/s^2[/tex]
1 kilogram meter per square second is equal to 1 Newton. Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.[tex]F= 252.5 \ N[/tex]
The force required is 252.5 Newtons.
9.) This 200 kg
stag that weighs
1,960 N on earth
would only weigh
324 N on the
moon. Calculate the moon's
acceleration due to gravity.
Answer:
Mass on moon = 33.06 kg
Explanation:
Given the following data;
Mass on earth = 200 kg
Weight on earth = 1960 N
Weight on moon = 324 N
To find the mass on moon;
First of all, we would determine the acceleration due to gravity.
Weight = mass * acceleration due to gravity
1960 = 200 * g
g = 1960/200
g = 9.8 m/s²
Next, we find the mass on moon;
Mass on moon = weight on moon/acceleration due to gravity
Mass on moon = 324/9.8
Mass on moon = 33.06 kg
