How do you calculate magnitude of acceleration?
α = (Fr sinθ)/m where F is the force acting on the object ..........r is the radius from the 'centre' of the object to the point of application of force. ..........θ is the angle between r and the vector of the force. ..........m is the moment of inertia of the object.
Energy needed to move 4 coulombs of charge is 4 joules .the potential difference is how much?
The potential difference is 1 volt = 4J/4C.
Is direction the course in which an object is moving?
No it isn't. Motion means something moving.Direction has to be established for there to be a change in it. An object that moves forward, stops, and then moves forward again experiences motion without a change in direction. An object that moves forward, stops, and then moves to the right experiences both motion and a change in direction.
Calculate the energy released when a 28.9 gram piece of copper is cooled from its melting point of 1083 àC to 25.0 àC The specific heat of copper is 385 Jg àC?
1.18x10^4j
How much heat must be added to make a 5g substance with a specific heat of 2 JgC that has its temperature go up 10 degrees?
42 j
How do you find the magnitude of a vector?
The magnitude of a vector can be found by taking the square root of each of the vector components squared. For example, if you had the vector 3i+4j, to find the magnitude, you take sqrt ( 3²+4² ) To get: sqrt ( 9+16 ) sqrt ( 25 ) = 5 Works the same in 3D or more, just put all the vector components in.
How do you find the magnitude and the direction of a vector when F3i-4j?
7
Find the resultant of three forces- F13i-4j 2kF22i 3j-kF32i 4j-5k?
Assuming you mean:F1 = 3i - 4j + 2k,F2 = 2i + 3j - k,F3 = 2i + 4j - 5k.Simply add all of them algebraically, i.e. add i's to i's, j's to j's etc. - this works in all dimensions.The resultant force F will be in your case:F = 7i + 3j - 4k.
-4j-1-4j plus 6?
-4j-1-4j+6 = -8j+5
Vector A plus vector B equals 2i and vectorA-vectorB equals 4j then angle between vectorA and vectorB is?
I've got to assume that your ' i ' and your ' j ' are the same thing.Vector A = j3Vector B = -j1The angle between them is (pi).
What is j equals 20-4j?
If: j = 20-4j Then : j = 4
How do you solve 3y-4j equals 9?
Express one variable in terms of the other. 3Y - 4J = 9 3Y = 4J + 9 Y = (4J + 9)/3 ------------------------ insert back into original equation 3(4J + 9)/3 = 9 you see the 3 factors cancel 4J + 9 = 9 4J = 0 J = 0 -------------you have J 3Y - 4(0) = 9 3Y = 9 Y = 3 ----------------one set of solutions to this problem
What is the value of j in the inequality 4j - 7 greater than 4j - 7?
I think you have entered the inequality wrong. You have: 4j - 7 > 4j - 7 but that is saying that something is greater than itself as both sides of the greater than sign are the same expression.

What is the product of j and 4?
4j
What is the answer to -4j equals 18 plus 5j?
The answer is the numerical value of 'j' that makes the equation a true statement.-4j = 18 + 5jAdd 4j to each side:0 = 18 + 9jSubtract 18 from each side:-18 = 9jDivide each side by 9:-2 = j
What is the answer to 4J-8 equals 92?
J=25.
