A car traveling at 60 km/h will skid 30 m when its brakes are locked. if the same care is traveling at 180 km/h, what will be th
Flauer [41]
The first car travels at 60km/h and skid at 30m away from the starting point while another car is also traveling at 180km/h. Now, we need to solve for the skidding distance.
We assigned variables such as:
V1=60km/h
V2=180km/h
Skid1=30m
Skid2=?
We solve this by ratio and proportion method such as shown below:
V1/V2=skid1/skid2
60/180=30/skid2
skid2=(30*180)/60
skid2=90meters

Th answer is 90 meters.

Two one-coulomb point charges are at a distance of 1.67 m from each other. What is the size of the electric force between the tw
pychu [463]

Explanation:

The given data is as follows.

       distance (r) = 1.67 m

     q_{1} = q_{2} = 1 C

It is known that formula for electric force between two charges is as follows.

          F = \frac{kq_{1} \times q_{2}}{r^{2}}

Hence, putting the given values into the above formula as follows.

       \frac{9 \times 10^{9} \times 1 \times 1}{(1.67)^{2}}

            = 3.227 \times 10^{9}

As it is given that mass of  Falcon Heavy rocket is 1421. Therefore, weight of 1 Falcon rocket is as follows.

       weight of 1 falcon rocket = 142 \times 10^{3} \times 9.8

Therefore, number of falcon rockets will be calculated as follows.

         No. of falcon rockets = \frac{3.227 \times 10^{9}}{142000 \times 9.8}

                              = 2.31897 \times 10^{3}

                              = 2318.9 falcons

Thus, we can conclude that force between the two point charges above is equal to the weight of 2318.9 Falcon Heavy rockets.
