Answer: it is D. it is the only possible answer. use the process of elimination. which answers make sense?
Answer:
R= 5.4 ohms
Explanation:
Given that
V= 9 V
Power ,P= 15 W
Lets take resistor resistance = R
We know that Power given as
V=Voltage
P=Power
R=Resistance
Now by putting the all the values in the above equation
R= 5.4 ohms
Therefore the resistance of the resister will be 5.4 ohms.
Answer:
The x - intercept is 1/3
The y - intercept is 1/2
The gradient is -3/2
Explanation:
To find the x - intercept of the equation 2y + 3x = 1, we find the value of x when y = 0. So,
2y + 3x = 1
2(0) + 3x = 1
0 + 3x = 1
3x = 1
x = 1/3
So, the x - intercept is 1/3
To find the y - intercept of the equation 2y + 3x = 1, we find the value of y when x = 0. So,
2y + 3x = 1
2y + 3(0) = 1
2y + 0 = 1
2y = 1
y = 1/2
So, the y - intercept is 1/2
To find the gradient of the equation 2y + 3x = 1, we re-write it in gradient intercept form by making y subject of the formula.
So, 2y + 3x = 1
2y = -3x + 1
y = -3x/2 + 1/2
The coefficient of x which equals -3/2 is the gradient.
The gradient is -3/2
Answer:
centripetal force is calculated by mass(kg) × tangetial velocity(m/s) ÷ radius (m)
Explanation:
so 30000g= 30kg
50km/h = 13.88m/s
600cm= 6m
30×13.88÷6= 69.4N
N= Newton's
hope this helps.
btw I'm 16 and love physics so I tried my best in this hope it went well!!
