Answer:
The weight of water weight is 5.043 N.
Explanation:
Given that,
Force = 4.78 N
Weight of steel bolt = 2.07 N
Density of steel = 7.86 g/cm³
Suppose determine how much does the glass of water weight.
We need to calculate the volume of bolt
Using formula of density
Put the value into the formula
We need to calculate the force on bolt
Using buoyant force
Put the value into the formula
We need to calculate the new weight of glass of water
Using formula for weight of glass of water
Put the value into the formula
Hence, The weight of water weight is 5.043 N.
Answer:
There is nothing faster then light
Explanation:
Just explain the day of how you were shopping and there you have it
Answer:
W = 650 [kJ]
Explanation:
The definition of work is denoted by the product of force by the distance traveled by the body, this distance traveled corresponds to the direction of the force.
In this case we have:
d = distance = 2.6[km] = 2600 [m]
F = force = 250 [N]
W = F*d = 250 * 2600 = 650000 [J] or 650 [kJ]
Joseph's experiment could be improved by using the same antenna at each part of the house during each trial instead of using different antenna. By doing so, he can obtain accurate results how is the signal in different part of the house under the same conditions (despite the location). So, he will see the dependence of the signal on the location. If he uses different antenna, than this antenna can also have influence of the signal.
