Answer:
Gravitational force, F = 1054.65 N
Explanation:
Given,
The accelerating speed, a = 15 m/s²
The mass of your body, m = 155 lbs
= 70.31 Kg
The gravitational force acting in a body is given by the relation
F = m x g
Where g is the acceleration due to gravity of the in which the velocity of the body changes its speed at a constant rate.
∴ a = g
Substituting the values in the above equation
F = 70.31 x 15
= 1054.65 N
Hence, the gravitational force acting on you, F = 1054.65 N
Answer:
Approximately .
Explanation:
Consider two objects of mass and . Let denote the distance between the center of mass of each object. Let denote the gravitational constant. (.)
By Newton's Law of Universal Gravitation, the size of gravitational attraction between these two objects would be:
.
In this question, and are the mass of the two planets. The distance between the two planets is (approximately the same as the distance between the center of mass of planet Earth and the center of mass of Mars.)
Apply Newton's Law of Universal Gravitation to find the size of gravitational attraction between the two planets:
.
Since , the size of gravitational attraction between the two planets would be approximately .
This is the correct answer to your question, "BC shows zero acceleration, and CD shows negative acceleration".
Answer:
he correct answer is Traffic accidents.
Explanation:
Chinese researchers have developed a car that needs the power of brain to operate. It is said to be country's first car that is operated by the mind. The researchers were worried due to the potential road accidents that was caused by the drivers distraction. They believed that concentration is required only while changing the lane or during turns (changing the moving status of car).
Answer:
Look Below -->
Explanation:
a. She traveled 10 km, add 4.5 km + 5.5 km = 10 km (Distance is the total units travelled, so just add them all up :) )
b. Her displacement is 0 km because she went back home. (Displacement is the difference between the end and starting points)
c. 3 km/hr (30 minutes / 10 km)
