Answer:

"A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families."

How much heat is needed to raise the temperature of 100 g of water by 50 C, if the specific heat of water is 4,184 J/kg.C?

Yuliya22 [10]

Heat required to raise the temperature of water is given as

$Q = ms\Delta T$

here we have

m = 100 g = 0.100 kg

s = 4183 J/kg C

$\Delta T = 50 ^0 C$

now we can use the above equation

$Q = 0.100 * 4184 * 50$

$Q = 20920 J$

so here it requires 20920 J heat to raise the temperature of 100 g water by 50 degree C

Can a runner on a track be accelerating even if she is running at a constant speed why or why not

Lynna [10]

If the runner is running in a circular track then yes when something or someone is moving in a circular motion at a constant speed they are indeed accelerating. They’re accelerating because the direction of the velocity vector is changing

A 58-kg boy swings a baseball bat, which causes a 0.140-kg baseball to move toward 3rd base with a velocity of 38.0 m/s.

Sophie [7]

Answer:
101 J
Explanation:
The kinetic energy of an object is given by

where
m is the mass of the object
v is its speed
For the baseball in this problem,
m = 0.140 kg
v = 38.0 m/s
Substituting into the equation, we find the kinetic energy of the ball:

A block mass m (0.25 kg) is pressed against (but is not attached to) an ideal spring of force constant k (100 N/m) and negligibl

VMariaS [17]

Answer:

d. All the above choices are correct.

Explanation:

When a spring of spring constant k is compressed by distance x , the potential energy stored in it is equal to

E = 1/2 k x²

If spring constant is 2 k , potential energy stored

E = 1/2 2k x²

= k x²

which is twice the earlier potential energy.

In the first case , the energy of spring is imparted to box . The energy given to box is spent by frictional force due to which box comes to rest.

So energy of box acquired from spring = work done by frictional force.

So energy of box acquired from spring = F X d , F is frictional force , d is displacement .

In the second case ,

energy acquired by box becomes two times

Work done by frictional force will also become two times to put box at rest

So displacement will be two times ( because frictional force is constant )

so option a is correct .

option b is also correct .

Because kinetic energy of box will be twice as explained above .

So option d will be correct.
