Answer: d = 33 cm or 0.33 m
Explanation: In physics, Work is the amount of energy transferred to an object to make it move. It can be expressed by:
W = F.d.cosθ
F is the force applied to the object, d is the displacement and θ is the angle formed between the force and the displacement.
For the ice block, the angle is 0, i.e., force and distance are at the same direction, so:
W = F.d.cos(0)
W = F.d
To determine d:
d = 
d = 
d = 0.33 m
The distance d the block ice moved is 33 cm.
behavior therapy is usually focused on increasing the person's engagement in positive or socially reinforcing activities. Behavior therapy is a structured approach that carefully measures what the person is doing and then seeks to increase chances for positive experience. AND Overcoming depression
The frequency of rotation of Mars is 0.0000113 Hertz.
<u>Given the following data:</u>
- Period = 1 day and 37 minutes.
To find the frequency of rotation in Hertz:
First of all, we would convert the the value of period in days and minutes to seconds because the period of oscillation of a physical object is measured in seconds.
<u>Conversion:</u>
1 day = 24 hours
24 hours to minutes = 
× 
= 
minutes
1 minute = 60 seconds
1477 minute = X seconds
Cross-multiplying, we have:
× 
X = 88620 seconds
Now, we can find the frequency of rotation of Mars by using the formula:
<em>Frequency </em><em>of rotation</em> = <em>0.0000113 Hertz</em>
Therefore, the frequency of rotation of Mars is 0.0000113 Hertz.

Answer:
2 m/s²
Explanation:
the equations of motion are
S= ut +½at²
v² = u²+ 2as
v = u + at
s = (u+v)/2 × t
From the parameters given
u = 0m/s this is because it starts from rest
Distance (s) = 9m
Time (t) = 3s
Based on this the first equation would be used
s = ut + ½at²
Input values
9 = 0×3 + ½ × a x 3²
9 = 0 + 9a/2
9 = 4.5a
Divide both sides by 4.5
a = 9 / 4.5 m/s²
a = 2 m/s²

Explanation:
A battery is an electrochemical cell that converts chemical energy into electrical energy. The chemical reactions in a battery ensures that current is produced.
- A battery is made up of two electrodes which are the cathode and anode.
- The cathode is the positive electrode and the anode is the negative one.
- These electrodes are made up of metals.
- Electrons moves from the anode to the cathode and current flows from cathode to anode.
- At the anode oxidation occurs because electrons are produced here.
- It needs to have low electron affinity.
- At the cathode where reduction occurs, the electron affinity must be high.
- This is the driving force for the production of electricity in electrochemical cells.
