Your shopping cart has a mass of 65 kilograms. In order to accelerate the shopping cart down an aisle at 0.30 m/s2 What force would you need to use or apply to the cart. I don't know how to solve this
Justin ! Justin ! ! You're in high school Physics. You've done Newton's Laws until you saw them in your sleep. When the wind rustles through the trees, you almost hear it whispering to you "F = M A". Now is the time to use that ! M=65kg. A=0.3m/s^2. F = (65)(0.3)=19.5 newtons.
How many miles can you get on one tank of gas if your tank holds 18 gallons and you get 22 miles per gallon?
Multiply the two. The units will cancel out. 22 miles per gallon can be expressed as 22 miles / 1 gallon, so you can write the following: 18 gallons * 22 miles / 1 gallon Which simplifies to 18 * 22 miles = 396 miles.
(10*22) + (8*22)=
The acceleration of gravity is a constant equal to _______ meters per second squared.A. 9.8 B. 8.4 C. 10.2 D. 7.6
The acceleration due to gravityis the acceleration on an object caused by force of gravitation. It means thatthe earth has a gravitational field that projects all bodies on earth towards itscenter. The gravity of an object or body of an object is high on earth than atthe atmosphere. It has an average of gravitational constant equal to 9.8066 or9.8 meters per second. In truth, the acceleration of the object depend upon itslocation, the latitude and altitude, on earth.
Convert 1 mm of Hg into pascal
1 millimeter of mercury is 133.322 pascals
Linus builds an electrical circuit with a battery and with wires that carry the current. As the battery weakens, the current also weakens. How does this affect the magnetic field around the wires? A. The field gets stronger.
B. The field gets weaker.
C. The field changes direction.
D. The field disappears completely.
Answer: The correct answer is option (B).
The current carrying wire produces the magnetic field around it. More the current in the wire, stronger will be the magnetic strength around the wire. The magnetic field is stronger near this wire.
The direction of the magnetic field depends on the direction of the current.
In the given problem, Linus builds an electrical circuit with a battery and with wires that carry the current.The strength of the magnetic field depends on the amount of current flowing in the wire. As the battery weakens, the current also weakens.
Therefore, the magnetic field around the wires is weaker.
The magnetic field getting weaker is the correct answer when Linus builds an electrical circuit with a battery and with wires that carry the current. The correct answer is (B).
The strength of the magnetic field around the wires is directly proportional to the current flowing through the wires. As the battery weakens and the current decreases, the magnetic field strength around the wires also decreases.
Conversely, if the current increases, the magnetic field strength increases. This relationship is described by Ampere's law and the right-hand rule, which state that the magnetic field is directly proportional to the current.
Therefore, The correct answer is (B). The magnetic field getting weaker is the correct answer.
two plane mirrors are at right angles to each other. a man stands between them and combs his hair with his right hand. in how many of the images will he be seen using his right hand? none 1 2 3
In the first two images the comb would be in the left hand of the man. The image which appears in between those two images has the comb in its right hand. Therefore, the images in which he will be seen using his right hand is one.
What is required to cause acceleration?
F = ma
Where m = mass of body, a = acceleration.
F = ma = m(v - u)/t
So for an acceleration to occur, a force is required.
Also a change of velocity is required for acceleration to occur.
