Answer:
24 miles
Explanation:
Make a proportion
He is traveling at a constant rate of 12 miles/hour, so
he can go 12 miles in 1 hour, and x miles in 2 hours
12/1=x/2
Multiply both sides by 2
2*12/1=x/2 *2
24=x
So, in 2 hours he can travel 24 miles
Explanation:
It is given that,
Length of the string, l = 2 m
Mass of the string, 
Hanged mass in the string, 
1. The tension in the string is given by :


T = 1.96 N
2. Velocity of the transverse wave in the string is given by :

m = M/l


v = 28 m/s
Hence, this is the required solution.
Wave speed= Frequency x Wavelength
-> Wavelength= Wave speed divide Frequency
-> 50m/s divide 100Hz= 0.5m
Iron is the best conductor in this group.
Contact area is not a factor of the amount of friction force acting between two bodies in contact, preventing rolling or sliding
Reasons:
- Friction force is the product of the normal reaction and the coefficient of friction.
- The coefficient of friction is higher in softer tires than hard tires which are required to be wider to reduce the pressure that can cause deformation withstood by hard tires.
- The wide tires in drag racing cars can be thought of being made from the soft compound tire material having a higher coefficient of friction that increases the friction force.
Other advantages of wide tires are;
- Shorter stopping distance
