Answer:
order of my age is 8 in seconds.
Explanation:
Suppose my age is 20 years.
Now, as we know that:
1 year has 365 days
1 day has 24 hours
1 hour has 60 minutes
1 minute has 60 seconds.
So my age in seconds will be:
Therefore the order of my age is 8 in seconds.
Answer:
2.22 m
Explanation:
According to literature, the highest abrupt deceleration the human body can experience and survive in a car accident is 250 m/s²
Using the equations of motion,
v² = u² + 2as
v = final velocity of the body = 0 m/s
u = initial velocity of the body = 120 km/h = 120 × 1000/3600 = 33.33 m/s
a = - 250 m/s²
s = ?
0² = 33.33² - (2×250×s)
500s = 1111.1111
s = 2.22 m
Y₀ = initial position of the balloon at the top of the building = 44 m
Y = final position of the balloon at halfway down the building = 44/2 = 22 m
a = acceleration of the balloon = - 9.8 m/s²
v₀ = initial velocity of the balloon = 0 m/s
v = final velocity of the balloon = ?
using the kinematics equation
v² = v₀² + 2 a (Y - Y₀)
inserting the values
v² = 0² + 2 (- 9.8) (22 - 44)
v = 20.78 m/s
Answer:
35.2 ps
Explanation:
Hello!
A US short ton is equal to 2 000 pounds, therefore:
2.25 tons = 4500 pounds
Now lets convert the area of each tire footprint:
1 cm = 0.393701 in
12.5 cm = 4.92126 in
16.5 cm = 6.49607 in
Therefore, the area of the footprint is: 31.9688 in^2
Then, the pressure exerted by the car is given by the weigth devided by the total area, that is 4 times the area of the footprint :
4500 /(4 * 31.9688) psi = 35.1906 psi
Rounding to the first tenth
35.2 psi
