Answer:
b. able to travel through a vacuum.
Explanation:
The most distinguishing factor of an electromagnetic waves is that they are able to travel through a vacuum.
These waves do not require materials in a medium for propagation.
- Electromagnetic waves are formed by the propagation of the electric and magnetic fields.
- They vibrate at an angle of 90° .
- They are unlike like mechanical waves that requires that requires materials in medium for their propagation.
Answer:
12 J
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 7.6 kg
Distance (d) = 6 m
Velocity (v) = 5 m/s
Force (F) = 2 N
Workdone (Wd) =.?
Workdone can be defined as the product of force and distance moved in the direction of the force. Mathematically, it is expressed as:
Workdone = Force × distance
Wd = F × d
With the above formula, we can obtain the workdone as follow:
Distance (d) = 6 m
Force (F) = 2 N
Workdone (Wd) =.?
Wd = F × d
Wd = 2 × 6
Wd = 12 J
Thus, the workdone is 12 J
We have that for the Question it can be said that The maximum height reached by the first <em>object</em> will be 100 times that of the other.
From the question we are told
One object is thrown vertically upward with an initial velocity of 100 m/s and another object with an initial velocity of 10 m/s. The maximum height reached by the first object will be
that of the other.
a. 10,000 times
b. none of these
<em>c. </em><em>1000 times</em>
d. 100 times
<em>e.</em><em> 10 times</em>
Generally the equation for the velocity is mathematically given as
Therefore
The maximum height reached by the first <em>object</em> will be 100 times that of the other.

Answer:
As with any wave the speed of sound depends on the medium in which it is propagating.
Explanation:
F=ma
=> 20=10m so m=2
Then the force is doubled 20.2=40
F'=ma'
m does not change so 40=2.a'
a'=20 which is option b.
