Given V = 60 volts of an outlet in a select country, and I = 0.5 amps are being pulled to the 60 watt bulb, solve V = IR in terms of R, and
substitute the given quantities. (1 point)
O R = 30 ohms
O R = 60 ohms
O R = 120 ohms
O R = 240 ohms
V = IR can be rearranged to solve for R:
R = V/I
Substituting the given values:
R = 60 volts / 0.5 amps
R = 120 ohms
Therefore, the correct answer is O R = 120 ohms.
Determine whether each equation is a valid or invalid rearrangement for the formula P = ‡(a + b) h. (2 points)
Valid
Invalid
2P = (a+b)h
2P/h =a+b
P= 1/2ah+bh
h= a+b/2P
2P = (a+b)h is a valid rearrangement of the formula P = ‡(a + b) h.
2P/h = a+b is a valid rearrangement of the formula P = ‡(a + b) h.
P= 1/2ah+bh is an invalid rearrangement of the formula P = ‡(a + b) h. The correct rearrangement would be P = ah + bh.
h= a+b/2P is an invalid rearrangement of the formula P = ‡(a + b) h. The correct rearrangement would be h = 2P/(a + b).
Genevieve and Jose are both planting square gardens. Jose's garden is 25 square feet and Genevieve's is 4 square yards. Convert their garden sizes to the same units (feet) to determine who's garden has a larger area. (1 point)
Genevieve's garden is 25 square feet, and thus, has the exact same area as vose's
Genevieve's garden is 12 square feet, and thus, has a smaller area than Jose's
Genevieve's garden is 36 square feet, and thus, has a larger area than Jose's
Genevieve's garden is 16 square feet, and thus, has a smaller area than Jose's
To compare the garden sizes, we need to convert Genevieve's garden size from square yards to square feet.
Since 1 yard is equal to 3 feet, and 1 square yard is equal to 3 feet * 3 feet = 9 square feet, we can convert Genevieve's garden size as follows:
Genevieve's garden size in square feet = 4 square yards * 9 square feet/square yard = 36 square feet.
Therefore, the correct answer is: Genevieve's garden is 36 square feet, and thus, has a larger area than Jose's.
The formula V = IR can be rearranged to solve for R. Dividing both sides of the equation by I, we have:
R = V / I
Substituting the given values, V = 60 volts and I = 0.5 amps:
R = 60 / 0.5
R = 120 ohms
Therefore, the value of R is 120 ohms. So, the correct answer is "R = 120 ohms".
To solve for R in terms of V and I using Ohm's law (V = IR), we need to rearrange the equation to solve for R.
Step 1: Start with the equation V = IR.
Step 2: Divide both sides of the equation by I.
V/I = IR/I.
Step 3: Simplify the equation.
V/I = R.
Now let's substitute the given quantities into the equation.
V = 60 volts
I = 0.5 amps
Substituting these values into the equation V/I = R, we get:
R = V/I
R = 60 volts / 0.5 amps
Simplifying this expression, we find:
R = 120 ohms.
Therefore, the correct answer is: O R = 120 ohms.
