Answer:
Explanation:
As we know that tank itself has mass given as 13.4 kg
so it is given as
also the tank contains air in it and the mass of air inside the tank is also given as 4.47 kg
so it is
so total mass of the tank is the mass of the empty tank and mass of air in the tank
Answer:
4 J
Explanation:
From the image attached, we can see 2 horizontal forces acting on the box albeit in opposite directions.
Now, the net force will be;
F_net = 3 - 1
F_net = 2 N
To move a distance of 2 metres, kinetic energy is;
K.E = Force × Distance = 2 × 2 = 4 J
Answer:
A major challenge in the drug delivery field is to enhance transport of therapeutics across biological barriers such as the blood brain barrier (BBB), the small intestine, nasal, skin and the mouth mucosa.
Answer:
<em>13 m/s²</em>
Explanation:
Mass of object = 200 Kg
Applied force = 2600 N
Acceleration = ?
Solution:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m (N = kgm/s²)
a = 2600 kgm/s² / 200 Kg
a = 13 m/s²
A force can cause an object with mass to change its velocity
The formula F = m x a.
Force = mass multiplied by acceleration.
The definition of a Newton,
the standard unit of force, is
Newton = kg × m/s^2.
(m/s = meters per second squared)
