Car traveled 1/10 mile in .002 hr
1/10 mi / .002 hr = 50 mi/hr
Answer:
68 ohm
Explanation:
Output Voltage, Vout = 5 V
Forward voltage, Vf = 3.65 V
Forward current, If = 20 mA = 0.02 A
Let the resistance is R.
Use the formula


R = 67.5 ohm
R = 68 ohm ( approx.)
Answer:
Weight of the object will be 98 N
Explanation:
We have given mass of the object m = 10 kg
Acceleration due to gravity 
We have to find the weight of the object
Weight of the object is dependent on mass and acceleration due to gravity, it is the product of mass and acceleration due to gravity
So weight of the object W = mass × acceleration due to gravity
So 
So weight of the object will be 98 N
