Answer:
If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks.
Answer:
Ф = 4.5176x10⁵ N . m² / C
Explanation:
In this case, we need to use two expressions in order to calculate the electric flux of the sphere.
First the Electric flux is calculated using this expression:
Ф = E * A (1)
Where:
E: Electric field
A: Area of the sphere
To get the electric field E, we use this expression:
E = K * q / r² (2)
If we replace (2) into (1) we have the following:
Ф = K * q * A / r² (3)
Finally, we need to know the expression to get the area of a sphere which is the following:
A = 4πr² (4)
Replacing into (3):}
Ф = K * Q * 4πr² / r² discarting r²:
Ф = K * Q * 4π (5)
Now, all we need to do is replace the given values and solve for the electric flux of the sphere:
Ф = 8.98755x10⁹ * 4x10⁻⁶ * 4 * π
<h2>
Ф = 4.5176x10⁵ N . m² / C</h2>
Hope this helps
Ans: A quantity cannot have units until it has dimensions. A quantity that has dimensions must have units. Yes a quantity have units but still be dimensionless for example,unit of angle is radian ,but it is a dimensionless quantity. A dimensionless quantity may have unit.
A. 4% you divide 2000 to 500 and you get 4 which is your answer
Answer:
0.114 kg or 114 g
Explanation:
From the diagram attaches,
Taking the moment about the fulcrum,
sum of clockwise moment = sum of anticlockwise moment.
Wd = W'd'
Where W = weight of the mass, W' = weight of the meter rule, d = distance of the mass from the fulcrum, d' = distance of the meter rule.
make W' the subject of the equation
W' = Wd/d'................ Equation 1
Given: W = mg = 0.0515(9.8) = 0.5047 N, d = (39.2-16) = 23.2 cm, d' = (49.7-39.2) = 10.5 cm
Substitute these values into equation 1
W' = 0.5047(23.2)/10.5
W' = 1.115 N.
But,
m' = W'/g
m' = 1.115/9.8
m' = 0.114 kg
m' = 114 g
