20 m/s
20 m/s
5 N
5 N
0.2 m/s
0.2 m/s
20 N
Answer:
The answer is 20 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
Force = mass × accelerationFrom the question
mass = 10 kg
acceleration = 2 m/s²
We have
Force = 10 × 2
We have the final answer as

Name 2 types of electric circuits based on their connection pattern
Answer:
When there are two or more electrical devices in a circuit with an energy source, there are a couple of basic ways by which we connect them. They can either be connected in series or parallel
[tex]\huge\bold\green{Answer:-}[/tex]
Series Circuit:-A series circuit has only one path for electricity to flow from one point to another. The amount of electricity in the circuit is consistent throughout any component in the circuit. When electricity flows through a series circuit, its rate of flow (speed) will never fluctuate. The total resistance of a series circuit equals the sum of individual resistances. The more resistors that a series circuit has, the more difficult it is for electrons to flow.
Parallel circuit:-A parallel circuit has multiple paths for electricity to flow from one point to another. According to website All About Circuits, “all components are connected between the same set of electrically common points.” Often, resistors and sources will be connected between two sets of electrically common points. In a parallel circuit, electricity can flow in multiple directions horizontally and vertically. The components of a parallel circuit will have the same voltage across their ends and will have identical polarities.

Answer:
The type of wave interaction occurred is destructive interference
Explanation:
Given that,
Max and Jimmy jump at same time.
Wave crest makes by Max and wave trough makes by Jimmy.
We need to find the type of wave interaction occurred
According to given data,
We know that,
If the wave crest and wave trough are interacted to each other then the interaction is destructive interference.
If the wave crest and wave trough are interacted with crest and trough then the interaction is constructive interference.
So, we can say that if the wave crest and wave trough are interacted to each other then the interaction is called destructive interference
Hence, The type of wave interaction occurred is destructive interference
Answer:
destructive interference

A granite monument has a volume of 25,365.4 cm. The density of granite is 2.7 g/cms. Use this information to calculate the mass of the monument to the nearest tenth. The mass of the granite monument is
Answer:
m = 68,486,6 g is the answer.
Explanation:
To calculate mass you use formula:
m= V*r
To avoid remembering this formula you can see the type of unit on each given variable. We can see that we have g/cm^3 and cm^3. If we multiply them, we negate cm^3 and cm^3 and we are left with g which is unit for mass.

An object can travel a distance of 20 meters at the same time that it has a displacement of zero.
A. True
B. False
Answer:
Yes
Explanation:
Yes, displacement can be zero even if the distance is not zero. For example, when a body is thrown vertically upwards from a point A on the ground, after some time it comes back to the same point A.
36 In the given circuit, A, B, C and D are four lamps connected with a battery of
60V.
Analyse the circuit to answer the following questions.
(i) What kind of combination are the lamps arranged in (series or parallel)?
(ii) Explain with reference to your above answer, what are the advantages (any
two) of this combination of lamps?
(iii) Explain with proper calculations which lamp glows the brightest?
(iv) Find out the total resistance of the circuit.
A parallel circuit, is one which the conductors leading into the bulbs are joined together on one side of the bulbs, and the conductors coming out of the bulbs are joined together on the other side of the bulb
The correct arrangement, advantages, lamp and resistance values are;
(i) The lamps are arranged in parallel(ii) Improved reliability Optimum performance of the bulbs(iii) Lamp C(iv) The total resistance is 4 ΩThe reason the above values are correct are as follows:
(i) From the diagram attached, the lamps are arrange in parallel
This is so because, each lamp is directly connected across the terminals of the the voltage source
(ii) The advantages of the bulbs arranges in parallel are;
The other lamps will continue working if one lamp becomes faultyThe voltage is applied directly to each lamp, such that the lamps are lit with the maximum power available in the circuit(iii) The brightness of the lamp is given by the power of the lamp
The lamp with the highest wattage, or power glows the most
Power, P = Voltage, V × Current, I
The power for lamp A, [tex]P_A[/tex] = 60 V × 3 A = 180 W
The power for lamp B, [tex]P_B[/tex] = 60 V × 4 A = 240 W
The power for lamp C, [tex]P_C[/tex] = 60 V × 5 A = 300 W (Brightest)
The power for lamp D, [tex]P_D[/tex] = 60 V × 3 A = 180 W
Therefore, lamp C has the highest power and glows the brightest
(iv) The total resistance is given by the voltage, divided by the total current
Total current, I = 3 A + 4 A + 5 A + 3 A = 15 A
[tex]Total \ resistance, \ R_{tot} = \dfrac{V}{I_{tot}}[/tex]
Therefore;
[tex]Total \ resistance, \ R_{tot} = \dfrac{60 \, V}{15 \, A }}=4 \, \Omega[/tex]
The total resistance, R = 4 Ω

an object falls from a high building and hits the ground in 9.0 seconds.ignoeing air resistance,what is the distance that it fell?
Answer:
kinematic eq. d = Vi*t + 1/2a*[tex]t^{2}[/tex]
Explanation:
Vi=0
d=1/2 a*[tex]t^{2}[/tex]
d= 1/2(9.8)[tex]0.9^{2}[/tex]
d=3.969 m
The distance from which the object falls is 393.9 meters.
Given that, an object falls from a high building and hits the ground in 9.0 seconds and air resistance = 0
So the distance can be calculated by the formula given below.
[tex]s = vt + \dfrac{1}{2} at^2[/tex]
Where, [tex]s[/tex] is the distance in meters, [tex]t[/tex] is time (in seconds) taken by the object in motion, [tex]a[/tex] is the acceleration of the object in meter per second square and [tex]v[/tex] is the final velocity in meter per second.
In this case, object falls from high building to the ground so the final velocity would be zero. Gravitational acceleration is -9.8 meter per second square.
Substituting the values in the above formula,
[tex]s = (9.0\times0) + \dfrac{1}{2}(-9.8\times(9.0)^2)\\s = 0 + (-9.8\times81\times0.5)\\s = 396.9 \;\rm m[/tex]
The distance from which the object falls is 393.9 meters.
