Answer:
Magnetic force, F = 0.6 N
Explanation:
It is given that,
Length of the wire, L = 30 cm = 0.3 m
Current carrying in the wire, I = 0.5 A
Uniform magnetic field, B = 4 T
To find,
The magnetic force
Solve,
A force is exerted by the wire in the magnetic field that is given by :
Here,
F = 0.6 N
Therefore, the magnetic force exerted by the wire in the magnetic field is 0.6 N
Assuming this coin is on earth and that it wasn’t dropped forcefully:
Use the formula d = 1/2at^2. Rewriting using a=g and solving for height h gets us h = 1/2(9.8)t^2.
In this case that would get that the change in height h is 0.5(9.8)(0.3^2) = 0.441 m.
Answer:
Explanation:
Relation between Celsius and Kelvin is
K = C + 273
Relation between Kelvin and Fahrenheit is
(a) 379 K
Relation between Celsius and Kelvin is
K = C + 273
So, C = K - 273 = 379 - 273 = 106
Thus, 379 K = 106°C.
(b) 379 K
Relation between Kelvin and Fahrenheit is
F = 222.8°F
Thus, 379 K = 222.8°F
(c) 1.04 x 10^2 K = 104 K
Relation between Celsius and Kelvin is
K = C + 273
So, C = K - 273 = 104 - 273 = -169
Thus, 104 K = - 169°C.
(d) 1.04 x 10^2 K = 104 K
Relation between Kelvin and Fahrenheit is
F =- 272.2°F
Thus, 104 K = - 272.2°F
Answer: The answer is in the figure attached.
Explanation:
The Work done by a Force refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
It should be noted that it is a scalar magnitude, and its unit in the <u>International System of Units</u> is the Joule (J). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter:
However, in the British Engineering and Gravitational Systems its unit is Foot-pound (ft-lb). Where
Now, when the applied force is constant and the direction of the force and the direction of the movement (traveled distance) are parallel, the equation to calculate it is:
So, taking into account the explanation above, the attached table shows the Work done for each situation.
