Answer:
10 times
Explanation:
The weight of the person is defined as the product of mass of person and the acceleration due to gravity of that planet.
Let the gravity is g.
W = m x g .... (1)
Now the value of g depends on the mass of earth when the radius of earth is constant.
g' = 10 g
So, W' = m x g' = m x 10 g = 10 mg = 10 W (from (1)
So, the weight of the person becomes 10 times.

Answer:
109.66km
Explanation:
Velocity is defined as the change in displacement of a body with respect to time.
Velocity = displacement/Time
Displacement = velocity * time
A truck is traveling due north at 75 km/hr approaching a crossroad and perpendicular road a police car is traveling west toward the intersection at 80 km/hr, then the resultant velocity is gotten using the pythagoras theorem since they are both perpendicular to each other.
v² = 75²+80²
v² = 5625+6400
v² = 12,025
v = √12,025
v = 109.66km/hr
If both vechicles reaches cross road in exactly one hour, the displacement of the truck with respect to the police car = 109.66km/hr * 1 hour
Displacement of the truck with respect to the police car = 109.66km
