True
Explanation:
Smooth = The tissue that is allowed to make the muscle
Cardiac = The layer that protects the heart and makes the heart stronger
Skeletal = The Bones In Your Body Allows For picking up heavy stuff if the muscles/bones grow
Answer:
C
Explanation:
To solve this question, we will need to develop an expression that relates the diameter 'd', at temperature T equals the original diameter d₀ (at 0 degrees) plus the change in diameter from the temperature increase ( ΔT = T):
d = d₀ + d₀αT
for the sphere, we were given
D₀ = 4.000 cm
α = 1.1 x 10⁻⁵/degrees celsius
we have D = 4 + (4x(1.1 x 10⁻⁵)T = 4 + (4.4x10⁻⁵)T EQN 1
Similarly for the Aluminium ring we have
we were given
d₀ = 3.994 cm
α = 2.4 x 10⁻⁵/degrees celsius
we have d = 3.994 + (3.994x(2.4 x 10⁻⁵)T = 3.994 + (9.58x10⁻⁵)T EQN 2
Since @ the temperature T at which the sphere fall through the ring, d=D
Eqn 1 = Eqn 2
4 + (4.4x10⁻⁵)T =3.994 + (9.58x10⁻⁵)T, collect like terms
0.006=5.18x10⁻⁵T
T=115.7K
Answer:
E) ΔP = F * R
Explanation:
Let's look at Ohm's law:
ΔV = I * R
where I is the electric current, ΔV is the potential difference and R is the resistance.
We can derive the relationship between pressure gradient (ΔP), blood flow (F), and resistance (R) by analogy, getting:
ΔP = F * R
or
F = ΔP/R
This means that the flow is proportional to the pressure difference and inversely proportional to the resistance.
Two forces 3N and 4N act on a body in a direction due north From East, the equilibrant's angle is given by .
<h3>What are equilibrium and resultant force?</h3>
The equilibrium force is the balanced force when the net force acting is zero and is the exact opposite of the consequent force. The resultant force is one single force replaced by numerous forces.
<h3>Briefing:</h3>
3N and 4N are the two forces pulling on a body.
The forces work along the North and the East, which are perpendicular to one another.
The resultant of the forces, which is provided by the equilibrant force,
R = √(3)²+(4)²
R = 5N
From East, the equilibrant's angle is given by
