The density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.
<h3>What is the relationship between acceleration and density?</h3>
For a solid falling through a viscous fluid, the acceleration of the object decreases until it attains terminal velocity.
The acceleration of the body increases with increase in density of the solid.
When density of solid = density of liquid, acceleration a = g
When density of solid = 2 × density of the liquid, acceleration a = g/2.
Therefore, the density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.

Answer:
It is a gene!!
Explanation:
It is because RNA is referred to as a gene. Genes are contained in chromosones.
Answer:
s = 2.65 m
Explanation:
given,
mass of block,M = 1.3 Kg
mass of bullet,m = 50 g = 0.05 Kg
speed of bullet,u = 250 m/s
speed of bullet after collision,v = 100 m/s
distance traveled by the block = ?
Assuming the angle of inclination of ramp equal to 40°
calculating the speed of the block
using conservation of momentum
M u' + m u = m v + M v'
initial speed of the block is equal to zero
0 + 0.05 Kg x 250 = 0.05 x 100 + 1.3 x v'
1.3 v' = 7.5
v' = 5.77 m/s
now, calculation of acceleration
equation the horizontal component
-mg sin θ = ma
a = - g sin θ
a = - 9.8 x sin 40°
a = -6.29 m/s²
using equation of motion for the calculation of distance moved by the block
v² = u² + 2 a s
0² = 5.77² + 2 x (-6.29) x s
12.58 s = 33.29
s = 2.65 m
hence, the distance moved by the block is equal to 2.65 m
Answer:
2.57 seconds
Explanation:
The motion of the ball on the two axis is;
x(t) = Vo Cos θt
y(t) = h + Vo sin θt - 1/2gt²
Where; h is the initial height from which the ball was thrown.
Vo is the initial speed of the ball, 22 m/s , θ is the angle, 35° and g is the gravitational acceleration, 9.81 m/s²
We want to find the time t at which y(t) = h
Therefore;
y(t) = h + Vo sin θt - 1/2gt²
Whose solutions are, t = 0, at the beginning of the motion, and
t = 2 Vo sinθ/g
= (2 × 22 × sin 35°)/9.81
= 2.57 seconds
Considering the volume of a rectangle, the volume of the tissue box is 3,239.1 cm³.
<h3>What is volume</h3>
Volume is a scalar-type metric quantity that is defined as the extension in three dimensions of a region of space. In other words, the volume corresponds to the space that the shape occupies.
<h3>Volume of a rectangle</h3>
To calculate the volume of a rectangle, it is necessary to multiply its 3 dimensions: length ×width×height. Volume is expressed in cubic units.
<h3>Volume of the tissue box</h3>
In this case, you know:
- Length: 11.8 cm
- Width: 12.2 cm
- Height: 22.5 cm
Replacing in the definition of volume of a rectangle:
Volume of the tissue box= length ×width×height
Volume of the tissue box= 11.8 cm× 12.2 cm× 22.5 cm
Solving:
<u><em>Volume of the tissue box= 3,239.1 cm³</em></u>
Finally, the volume of the tissue box is 3,239.1 cm³.
