Answer: composition, its size and shape.
Explanation:
All objects have <u>a frequency that characterizes them</u>, which is called <u>natural frequency</u>. This means that if a disturbance or vibration is emitted near the object, it will begin to vibrate due to its natural frequency.
It should be noted that there are objects that have more than one natural frequency, and this depends on the composition of the object, its elasticity, its shape and size.
Answer:
3.5m/s^2
Explanation:
From Newton's second Law of Motion
F = ma
Where F is the applied force, m is the mass of the object and a is the acceleration.
F = 350 N
Mass = 100kg
350N = 100×a
a = 350/100
a = 3.5m/s^2
The acceleration of the object will be 3.5m/s^2
Answer:
Magnitude of Vector = 79.3
Explanation:
When a vector is resolved into its rectangular components, it forms two vector components. These components are named as x-component and y-component, they are calculated by the following formulae:
x-component of vector = (Magnitude of Vector)(Cos θ)
y-component of vector = (Magnitude of Vector)(Sin θ)
where,
θ = angle of the vector with x-axis = 27°
Therefore, using the values in the equation of y-component, we get:
36 = (Magnitude of Vector)(Sin 27°)
Magnitude of Vector = 36/Sin 27°
<u>Magnitude of Vector = 79.3</u>
An object or any location can be represented on a two-dimensional surface like a paper or computer screen. This representation is known as map. Most maps do not take into account the elevation of the object or the location they representing. On the other hand, Topographic maps use contour lines to represent the third dimension and to show elevation change on or below the surface of the earth.
Answer:
<h2>
30 miles/hour, and 2.24 miles/hour</h2>
Explanation:
What is average speed?
It is the total distance traveled divided by the time taken to cover the total distance traveled
Given that the various distances are
20 miles and 10 miles
the total distance traveled is 20+10= 30 miles
the average speed is expressed as
average speed= total distance/time taken
average speed= 30/1
average speed= 30 miles/hour
The average velocity is a vector quantity
the velocity is the average displacement divided by time taken
average velocity= displacement / time
average velocity= 2.24 /1
average velocity= 2.24 miles/hour
