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

What type of nuclear radiation is emitted when carbon-14 decays
dalvyx [7]

Answer:

Beta radiation

Explanation:

Beta radiation is a radioactive phenomenon of nuclear decay in which an unstable atom or isotop, by transforming a neutron into a proton, or by transforming a proton into a neutron, becomes stable. For example, the decay of carbon 14 produces beta radiation.

C. The object is not in motion, ruling out A. We are not adding mass in any way, nor does adding heat to object increase its mass, therefore also ruling out B. Finally, we are not changing the object's position in such a way that gives it a higher ability to do work, ruling out D.

(a) How many kilograms of water must evaporate from a 60.0-kg woman to lower their body temperature by 0.750ºC?
Mrrafil [7]

Answer:

69.69 g

Explanation:

Evaporation of water will take out latent heat of vaporization.  Let the mass of water be m and latent heat of vaporization of water be 2260000 J per kg

Heat taken up by evaporating water

= 2260000 x m J

Heat lost by body

= mass x specific heat of body x drop in temperature

60 x 3500 x .750  ( specific heat of human body is 3.5 kJ/kg.k)

= 157500 J

Heat loss = heat gain

2260000 m= 157500

m = .06969 kg

= 69.69 g
