A 2300 kg truck has put its front bumper against the rear bumper of a 2400 kg SUV to give it a push. With the engine at full pow

er and good tires on good pavement, the maximum forward force on the truck is 18,000 N.What is the maximum possible acceleration the truck can give the SUV?

Answer:

3.8 m/s^2

Explanation:

We can solve this problem by applying Newton's second law, which states that:

F=ma

where

F is the net force on an object

m is the mass of the object

a is its acceleration

In this problem, we have:

m = 2300 + 2400 = 4700 kg is the total mass of the truck+the SUV

F = 18,000 N is the force exerted by the engine (that must be used to accelerate both the truck and the SUV)

Therefore, the acceleration on the truck-SUV system is

a=\frac{F}{m}=\frac{18,000}{4700}=3.8 m/s^2

True or False: The energy increase of an object acted on only by a gravitational force is equal to the product of the object's w
tamaranim1 [39]

Answer:

False.

Explanation:

The statement shown in the question above is false and this can be confirmed by Newton's law on universal gravitation. According to Newton, the gravitational force exerted on any body is proportional to its weight, but the distance that the object travels when falling is disproportionate. In addition, if the force resulting from the weight of the object and its displacement has an angle of 0º, the weight force of that object will provide an increase in kinetic energy.

Answer:

hi is

Explanation:

Ans. (1) For preparing vaccines, in olden days,microbes were injected in the bodies of horses ormonkeys. These laboratory animals used to makeantibodies to defend these microbes. Antibodies areproteins which can act against the disease-causinggerms. These antibodies were extracted from theblood of these animals and were used as vaccines.(2) Now-a-days with the advent of biotechnology,the vaccines are manufactured in laboratories withthe help of bacteria. For this purpose, a detailedstudy of the disease causing germ is undertaken.The genes and the DNA of such microbes arethoroughly explored. Then based on thisinformation, proteins which can act against suchmicrobes are synthetically prepared in thelaboratories. The safe vaccine is produced in such away which can defend the body against infections.3) Some types of vaccines are prepared from theextracts of germs. These germs or microbes aredeactivated and made dormant. When they areinjected in the body of a person, they initiate thedefending action. The body of such vaccinatedperson, already develops the antibodies in his or herbody. When in future, this person is again attackedby similar germs the defence starts immediately andthe person does not become sick.

You have two forces, 114.6 N and 70.7 N. What is their resultant (magnitude) if the first acts upward and the second acts downwa
PtichkaEL [24]

Hi there!

If they are in opposite direction:

- Let UP be the POSITIVE direction and DOWN be the NEGATIVE direction.

Thus:

∑F = 114.6 - 70.7 = 43.9 N upward

If they are in the SAME, downward direction:

∑F = -114.6 - 70.7 = -185.3

The magnitude is the absolute value, so:

|-185.3| = 185.3 N downward
