Answer:
Vesicular texture refers to volcanic rocks that contain holes called vesicles that were formed by gas bubbles in lava. This igneous rock is called scoria. The vesicles form from escaping gas bubbles in cooling lava.
The characteristics of electromagnetic waves typically represent as follows:
Keywords: the characteristics, electromagnetic waves, transverse, vacuum, electric fields, magnetic, perpendicular, propagation, Maxwell, Faraday, the speed, polarization, reflection, refraction, interference, and diffraction
Answer: reflection
Refraction
Energy
Speed
Explanation:
Reflection results when em wave hits a plane surface and returns in the same angle it incident
Refraction is the change in velocity and direction of em wave as it crosses boundaries of different medium
The energy of em wave is evenly distributed in electric field and magnetic field
The speed of em wave is the same as 3×10^8
Answer:
Explanation:
At t = 1 velocity = 0
At t = 3 velocity = 3
slope of the line = 3-0 / 3-1 = 3/2
At t = 2
velocity = 3/2 x ( 2 - 1 )
= 1.5 m /s
velocity at t = 2 is 1.5 m /s
Position at t = 2 :
displacement at t = 2
area of graph upto t = 2
= 1 / 2 x 1 x 1.5 = .75
position at t = 2 :
= initial position + displacement
= 10 + .75 = 10.75 m
position at 6 s :
displacement at t = 6
area of curve upto t = 6
= 1 / 2 x 2 x 3 + 3 x 3 + 1/2 x 3 x ( 4.5 - 3 )
= 3 + 9 + 2.25
= 14.25 m
position at t = 6
= initial position + displacement
= 10 + 14.25 = 24.25 m
position at 9 s :
displacement at t = 9
area of curve upto t = 9
= 1 / 2 x 2 x 3 + 4 x 3 + 1/2 x 4 x ( 5 - 3 )- 1/2 x 2 x 1.5
= 3 + 12 + 4 - 1.5
= 17.5 m
position at t = 9
= initial position + displacement
= 10 + 17.5 = 27.5 m
b. the risk of cancer associated with eating GM food.
c. increased resistance of insects to pesticides because of the pesticides resistance of GM crops.
d. the loss of consumer support.
Answer:
I think the Answer is B. Longitudinal waves
b. False
Answer: True
Explanation:
A chemical reaction in which the oxidation number of an atom, ion or molecule changes due transfer of electrons between two reactants is known as oxidation-reduction reaction or redox reaction. In Redox reaction, the oxidising agent brings oxidation by gaining electrons and reducing it self.
Example:
Zn + Cu²⁺ → Zn²⁺ + Cu
Here, Cu²⁺ is an oxidizing agent which got reduced to Cu .
Thus, the given statement is true.
It's true that in an oxidation-reduction reaction, the oxidizing agent always undergoes reduction. The oxidizing agent is a substance that is capable of oxidizing other substances, meaning it causes them to lose electrons. By taking these electrons, the oxidizing agent itself is reduced.
In an oxidation-reduction reaction, also known as a redox reaction, the statement that the oxidizing agent always undergoes reduction is indeed true. The oxidizing agent is a substance that has the ability to oxidize other substances, meaning it causes them to lose electrons. In taking these electrons, the oxidizing agent itself is reduced. This is due to the principle that in a redox reaction, when one substance is oxidized (loses electrons), another substance must be reduced (gain electrons).
#SPJ6
Answer:
Car B
Explanation:
Inertia of a body is the property to oppose its state of rest or state of uniform motion. It is also equivalent to the measure of its mass. Newton's first law of motion is also called as law of inertia.
According to given question, we have to write the name of car having more inertia. So, the body having more mass will have more inertia.
The mass of car A is 1500 kg while the mass of car b is 2000 kg. Hence, car B will have more inertia.
