Answer:

The acceleration is 1 cm/s^2.

Explanation:

The acceleration is defined as the rate of change of velocity.

Here, initial velocity, u = 3/1 = 3 cm/s

final velocity, v = 4/1 = 4 cm/s

time, t = 1 s

Let the acceleration is a.  

Use first equation of motion

v =  u + at

4 = 3 + 1 x a

a = 1 cm/s^2

A moving object is in equilibrium. Which best describes the motion of the object if no forces change?
Alchen [17]
If the object is in equilibrium that means that the sum of the forces on it is zero and the net force is zero. If none of the forces changes then the object continues in constant uniform motion. That means constant speed in a straight line.

How many moles of nitrogen are needed to completely convert 6.34 mol of hydrogen?
____ [38]
If we use the equation:
N2 + 3H2 --> 2NH3
Then
1 mol of Nitrogen required 3 moles of Hydrogen
x mols : 6.34mols
X = 6.34/3
X = 2.11 moles of Nitrogen are required.

Object with more momentum will take
inn [45]

Answer:

240 kg * m/s

Explanation:

Given

mass (m) = 60 kg

velocity (v) = 4 m/s

Momentum = ?

We know that

Momentum is the product of mass and velocity so

Momentum = m * v

                   = 60 * 4

                   = 240 kg * m/s

Hope it helps :)
