Answer:
1 L = 1000 cm^3
1 m^3 = 1000 L = 10^6 cm^3
1 m^3 = 10^6 g = 10^3 kg density of water
M = Density * Volume
V = 2 * 4 * 5 = 40 m^3
M = 10^3 kg / m^3 * 40 m^3 = 4.0 * 10^4 kg
The awnswer is .5 north (trust me i learned this)
A, both potential and kinetic energy as mechanical energy is the sum of potential and kinetic energy.
Answer:
5.03 m/s
Explanation:
Give
Speed = v = 24m/s
Wavelength = λ = 30cm = 0.3m
Amplitude = A = 1.0cm = 0.01m
The velocity of a point in Simple Harmonic Motion
at any time t is given by the following formula
v = ωA cos ωt
The value is the Maximum when cosωt.
The maximum value of cosωt. is 1.
Hence the maximum velocity is ωA
Velocity of the wave v=n λ
n = v/ λ = 24 /0.3 = 80
ω = 2πn = 2π*80 = 502.86 rad/s
Maximum velocity of the particle is
ωA = 502.86 * 0.01 = 5.03m/s
1. To solve this problem, you must apply formula of Universal Gravitation Law, which is shown below:
F=Gm1m2/r²
F=2.75x10^-12
G=6.7x10^-11
r=2.6 m
m2=2m1
2. You must clear m1, as below:
F=G(m1)(2m1)/r²
F=G(2m1)²/r²
m1=√(Fr²/2G)
3. When you susbtitute the values into the formula m1=√(Fr²/2G), you obtain:
m1=√(Fr²/2G)
m1√0.13
m1=0.37
m2=2m1
m2=2(0.37)
m2=0.74
4. Therefore, the answer is:
m1=0.37
m2=0.74
