The approximate distance between mars and earth is about 1.34 × 108 miles. how many seconds would it take for tv pictures transmitted from the viking space vehicle on mars's surface to reach earth? enter your answer in scientific notation.

Time taken from transmission = 719.61 seconds or  11.99 minutes

Explanation:

Given data:

The distance between the mars and the earth = 1.34 × 10⁸ miles

Now, converting the distance into meters

1 mile = 1.61 km = 1610 m

thus, we have

1.34 × 10⁸ miles = 1610 × 1.34 × 10⁸ m = 2.1574 × 10¹¹ m

Now, the picture will travel with the speed of light i.e 2.998 × 10⁸ m/s

also,

Time = Distance/speed

thus we have,

Time taken from transmission = (2.1574 × 10¹¹ m)/(2.998 × 10⁸ m/s)

or

Time taken from transmission = 719.61 seconds or (719.61/60 = 11.99 minutes)

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
