The situation narrated above is a geometric sequence with first term equal to 10 and the common ratio equal to 0.87. Since there is no telling as to how low will the bounce be, the sequence is infinite.
The equation for the sum of the terms in an infinite geometric sequence with common ratio that is lesser than 1 is,
S = Ao/(1 - r)
Substituting,
S = (10 ft) / (1 - 0.87)
S = 76.923
We multiply the sum by two.
2S = 76.923 x 2 = 153.846
We subtract 10 from this because the first bounce does not travel twice.
<em>ANSWER: 143.846 ft</em>
Answer:
Mass of the man = 100 kg
Explanation:
Given that,
Mass of the Earth, M = 6×10²⁴ kg
The radius of the Earth, r = 6400 km
Force on man, F = 977 N
We need to find the mass of the man. Let the mass of the man be m. The gravitational force acting between two objects is given by :
or
m = 100 kg
So, the mass of the man is 100 kg.
Answer:
1) 1.67eV
2) 505nm
Explanation:
The maximum kinetic energy of photoelectrons ,
KEmax=λhc−W=(0.3×10−6)(1.6×10−19)(6.62×10−34)(3×108)eV−2.46eV=1.67eV
If λ0 is the cut-off wavelength, W=λ0hc
or λ0=Whc=2.46×1.6×10−19(6.62×10−34)(3×108)=5.05×10−7m=505×10−9=505nm
<em>We know that the work function is the minimum photon energy for taking place of photoelectric effect. </em>
Answer:
Eleven non-metals are gases at room temperature, including oxygen and chlorine. One non-metal, bromine, is a liquid at room temperature. The other non-metals are solids at room temperature, including carbon and sulfur.
