Answer:
d) 289.31 m
Explanation:
Energy provided by potential energy = mgh = m x 9.8x 200 sin10.5 = 357.18m
Energy used by friction = μmgcos 10.5 x 200 = .075 x m x 9.8 x cos 10.5 x200 = 144.54 m .
Energy used by friction on plain surface = μmg x d.( dis distance covered on plain ) =.075x m x 9.8 xd = .735 m d
To equate
357.18 m -144.54 m = .735 m d
d = 289.31 m .

Answer:
2.4 × 10 ²¹ N/C
Explanation:
The lead-196 nucleus has 82 proton
Q ( charge on the nucleus ) = 82e where e = 1.602 × 10⁻¹⁹ C
Q = 82 × 1.602 × 10⁻¹⁹ C = 1.314 × 10⁻¹⁷ C
vp ( volume of proton ) = 4/3π r³
V, volume of lead nucleus = 4/3πR³
4/3πR³ = 196 × 4/3π r³
R = ∛(196r³) = 5.81 r = 5.81 × 1.20 ✕ 10⁻¹⁵ m = 6.97 × 10⁻¹⁵ m
magnitude of the electric field = KQ/R² = 8.99 × 10⁹ × 1.314 × 10⁻¹⁷ C / (6.97 × 10⁻¹⁵ m )² = 2.4 × 10 ²¹ N/C
Find stress using the formula Stress = Force / Area. Here, force
exerted by 85kg person on stool is F = mg = 85kg * 9.8 m/s^2 = 833N. Find total
area of 3 legs A = 3 π (D/2)^2 = 3 π (2.5 x 10^-2 / 2)^2 = 1.4726 x 10^-3 m^2.
Now substitute in Stress = Force/Area. Stress = 833N / 1.4726 x 10^-3 m^2 =
5.656 x 10^5 N/m^2. Find strain using the formula strain = Stress / Young’s
modulus. For wood, Y = 1.3 x 10^10 N/m^2. Thus, strain = 5.656x10^5 N/m^2 /
1.3x10^10 N/m^2 = 4.35 x 10^-5 = 0.00435%.
Therefore, the legs decrease by 0.00435%
Answer:
The volume of the balloon wil increase to the double of the initial volume.
Explanation:
p2= p1/2
p1*v1= p2*v2
p1*v1= p1/2 * v2
p1*v1 / p1/2 = v2
2* v1 = v2
