There is a(n) __________ relationship between an object's weight and its mass.

Mkey [24]

There is a direct relationship between between an object's weight and its mass.

Weight is actually the force of gravity on the object's mass and it can be calculated by multiplying the object's mass and the acceleration due to gravity. The higher the mass, the higher the weight and the lower the mass, the lower the object's weight. Thus, the relationship is direct.

A bumblebee has a charge of 1.0 µC is placed 10.0 cm from a charge of 2.5 µC. What is the magnitude of the electric force?

allochka39001 [22]

Answer:

F = 2.25 N

Explanation:

Given that,

Charge 1, $q_1=1\ \mu C = 10^{-6}\ C$

Charge 2, $q_2=2.5\ \mu C=2.5\times 10^{-6}\ C$

Distance between charges, d = 10 cm = 0.1 m

We need to find the electric force between charges. The formula that is used to find the electric force is given by

$F=\dfrac{kq_1q_2}{d^2}\\\\F=\dfrac{9\times 10^9\times 10^{-6}\times 2.5\times 10^{-6}}{(0.1)^2}\\\\=2.25\ N$

Hence, the force between charges is 2.25 N.

A light plane is headed due south with a speed of 200 km/h relative to still air. After 1.00 hour, the pilot notices that they h

Lilit [14]

Answer: the total velocity of the air is 67.69km/h to the north and 35.4km/h to the east.

Explanation: The initial velocity of the plane is 200km/h south (supose that south is our positive x-axis here and east is the positive y-axis)

In one hour, the plane is located 137km away from the initial position, and the position in X is equal to 137km*cos(15°) = 132.33, this means that the velocity in the x axis is equal to 132.33 km/h, knowing that the initial velocity of the plane was 200km in the x-axis, this means that the velocity of the air must be:

132.33km/h - 200km/h = -67.69km/h

km and the position in "y" is equal to 137km*sin(15°) = 35.4km

This means that the velocity of the air in the y-axis is 35.4km/h

So the total velocity of the air is 67.69km/h to the north and 35.4km/h to the east.

A car has a speed of 12m/s. The mass of the car and its passengers is 1250 kg. What is the total momentum of the car/passengers?

Temka [501]

Answer:

15000kgm/s

Explanation:

Given parameters:

Speed of the car = 12m/s

Mass of car and passengers = 1250Kg

Unknown:

Momentum of the car = ?

Solution:

Momentum is the quantity of motion a body posses;

Momentum = mass x velocity

Now insert the given parameters and solve;

Momentum = 12 x 1250 = 15000kgm/s
