Answer:
Volume of secret cavity = 4 x 10⁻⁶m³
Explanation:
The weight of the sculpture in air is 15.76 N
Mass of the sculpture = 1.61 kg
Mass = Volume x Density
1.61 = V x 8470
Volume of brass =1.90 x 10⁻⁴ m³
When it is submerged in water, the weight is 13.86 N.
That is
Weight of sculpture - Weight of water displaced = 13.86 N
15.76 - Weight of water displaced = 13.86
Weight of water displaced = 1.9 N
Mass of water displaced = 0.194 kg
Mass = Volume x Density
0.194 = V x 1000
Volume of water displaced =1.94 x 10⁻⁴ m³
Volume of secret cavity = Volume of water displaced - Volume of brass material
Volume of secret cavity = 1.94 x 10⁻⁴-1.94 x 10⁻⁴ = 0.04x 10⁻⁴ = 4 x 10⁻⁶m³
Answer:
0.00461031264 m/s
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of the Earth = 6 × 10²⁴ kg
r = Distance between Earth and Sun = 
t = Time taken = 3 days
Acceleration is given by
Velocity of the star
The Sun's speed will be 0.00461031264 m/s
3. Plastic rubbed in hair would make the plastic negatively charged and the hair positively charged. This means that the attractive force between the paper and plastic is greater than the repulsive force between paper and plastic. The net result is an attraction between the paper and the plastic.
1. false 2. D ex: its just light not heat, 2. its actually between microwaves and violet light but that's not an answer so <span> ¯\_(ツ)_/¯</span>
Answer:
Given:
Initial velocity (u) = 0 m/s
Final velocity (v) = 44 m/s
Acceleration (a) = 5 m/s²
To Find:
Time taken (t)
Explanation:
From equation of motion we have:
By substituting value of u, v & a in the equation we get:
