To simplify his insane equation, do M*G*H (Mass*Gravity*Height)
so like this.
2 (Mass)*9.8 (Gravity)*40 (height)
then when you multiply, you get
784 kg m^2/s
Answer:
3.03°
Explanation:
Given that
Height of the tree branch, h = 4.5 m
Distance of the veterinarian away, d = 85.5 m
The vet is to aim at the monkey at a particular angle. If we consider the force of gravity that will be acting on the dart. Then the angle that will be needed will be calculated as this.
So the angle is
Tan θ = opposite / adjacent
Tan θ = 4.5 m/ 85.5 m
Tan θ = 0.053, then
θ = Tan^-1 (0.053)
θ = 3.03°
Therefore, the angle needed is 3.03°
Answer:
1287.5 N
Explanation:
We are given that
Mass of vehicle ,m=2100 kg
Weight of vehicle ,F=20,600 N
Area,A=
We have to find the minimum force that must be applied to the attached piston of area in order to lift the vehicle.
Apply the pascal's law
Answer:
A.) 411.6 Mega metres
B.) 411.6 × 10^18 Picometers
Explanation:
Given that One light-year is the distance light travels in one year. This distance is equal to 9461 1015 m.
After the sun, the star nearest to Earth is Alpha Centauri, which is about 4.35 light-years from Earth.
The distance travelled will be
Distance = 9461 1015 × 4.35
Distance = 411557915.3 m
To Express this distance in
a. megameters, divide the value by 1000000
411557915.3 / 1000000
411.5579153 Mega metre
411.6 Mega metres approximately
b. picometers, multiply by 10^12
That is, 411557915.3 × 10^12
411.6 × 10^18 Picometers
the answer is D. A magnesium atom donates two electrons to the fluorine atoms → Each fluorine atom accepts one of the electrons → The magnesium atom becomes a +2 ion → Each fluorine atom becomes a -1 ion
because magnesium only has 2 valence electrons, and it would be easier to lose electrons rather gain.
i just took the test, its right.
