Answer : Acceleration of the car is 17.89\ m/s^2

Explanation :

Initial velocity of the car, u = 0 miles

Final velocity of the car, v = 80 miles/hour = 35.77 m/s

Time taken, t = 2 s

So, from the above data we are focusing on the velocity of the car w.r.t to time i.e. acceleration of the car.

a=\dfrac{v-u}{t}

a=\dfrac{35.77\ m/s-0}{2\ s}

a=17.89\ m/s^2

So, the car of the car is 17.89\ m/s^2

Hence, this is the required solution.

Green light has a lower frequency than blue light. Which color of light has a longer wavelength?
VashaNatasha [74]
Although green light has a lower frequency than the blue light, but green light has the longer wavelength than the wavelength of blue light. The wavelength of green light is longer by a small margin than the wavelength of the blue light. Red light has the highest wavelength among all the available colors of light. Any color of light is nothing but an electromagnetic wave that enables us to see things around us. Humans mostly can see wavelengths between the Electromagnetic spectrum and the Ultra violet region.

A unit of time sometimes used in microscopic physics is the "shake". One shake equals 10−8 s.
Lady_Fox [76]

Answer:

(a) There are 3.17 times more shakes in a second than seconds in a year.

(b) Humans have existed for 9067.72 universe seconds.

Explanation:

(a) First we calcule how many seconds are in a year. One year have 365 days, one day has 24 hours, one hour has 60 minutes and one minute has 60 seconds, so:

60s*60*24*365=3.1536*10^7s

Now, we calculate how many shakes are in a second:

1s*\frac{1shake}{10^{-8}s}=10^8shakes

Finally, we calculate how many more shakes in a second are there than seconds in a year:

\frac{10^8s}{3.1536*10^7s}=3.17

(b) Using a simple rule of three we can calculate  how many "universe seconds" have humans existed, recall that 1 day has 86400 seconds:

1010 years--------->86400s

106 years----------> x seconds

x=\frac{106y*86400s}{1010y}=9067.72s

A golfer tees off and hits a golf ball at a speed of 31 m/s and at an angle of 35 degrees. What is the horizontal velocity compo
marishachu [46]
To calculate the horizontal velocity component, use the cosine identity. where cos A = a / h
where A is the angle the golfer hits the ball
a is the horizontal component velocity
h is the speed the golfer hits the ball

so a = h cos A
a = 31 cos 35
a = 25.4 m/s
