Answer:
towards right so it is -15 degree
Explanation:
Net force in forward direction due to all three is given as
here we know that
Similarly in Y direction we will have
Now the net force on the donkey is given as
Now direction of force is given as
towards right so it is -15 degree
Answer:
157.9 kg
Explanation:
Density: This can be defined as the ratio of the mass of a body and it's volume.
The S.I unit of density is kg/m³.
From the question,
Density = Mass/volume
D = m/v............................ Equation 1
Where D = Density of gold, m = mass of gold, v = volume of gold.
make m the subject of the equation
m = Dv.................... Equation 2
Since the gold is a cube,
v = l³................... Equation 3
Where l = length of the gold cube.
Substitute equation 3 into equation 2
m = Dl³............... Equation 4
Given: D = 19300 kg/m³, l = 0.2015 m
Substitute into equation 4
m = 19300(0.2015)³
m = 157.9 kg.
Answer:the answer should be dark energy
Explanation:
Because acceleration depends not only on the change in velocity.
It also depends on the time during which the change occurs.
The formula is
Acceleration = (change in velocity) divided by (time for the change) .
Maybe Sla changed his velocity in 3 seconds, but Hazel
took all morning to change hers. In that case, even though
the amounts of change were equal, the times were different,
so the quotients of (change/time) were different.
