A small sphere with a charge of − 0.60 μc is placed in a uniform electric field of magnitude 1.2 × 106 n/c pointing to the west.

The entire and thorough solution is included.

Answer:

1350 m/s

Clarification:

Bullet speed

The bullet travels 450 m

Sound travels a distance of 450 m

Using the equation S= V × t

==> t= S/V

Thus, the time for the bullet t1=450/vb

and the sound's travel time t2=450/vs

Given that there's a 1/2 sec interval from when the shot is fired to the moment the shooter hears the sound

==>  t1+t2= 1/2 sec

==> 450/vb+450/vs=0.5sec  ---- (1)

At a distance 'x' from both the gun and target, it takes 3 seconds for a person to hear the bullet sound from firing to impact.

Firing sound duration

n

Distance =x m

Speed of sound = V

time =T1

==> T1 = x/vs

During this time period, the bullet covers 450 m and the sound of impact travels a distance 'x'

The time taken for sound = 450/vb

The time it takes sound to travel distance 'x'= x/vs

therefore let T2= 450/vb + x/vs

However, all this occurs within 3 seconds, i.e., T = 3 sec

because firing takes place before hitting the target, implying the strike sound is heard in time T = T2-T1= 450/vb + x/vs -x/vs

Making T= 3sec

==> 3= 450/vb

==> vb= 1350 m/s

From equations 1 and 2

applying the same principle, in 3 seconds the observer sees the bullet travel 450 m and perceives the sound

Response/Clarification:

Each of us receives 2 versions of a gene from our parents, with one inherited from the mother and one from the father.

Both our mother and father possess 2 versions of every gene. Therefore, the specific version we inherit is determined randomly, much like the outcome of a coin flip. This applies to both parents.

For instance, if the mother has one variant causing thick ears (A) and another for thin ears (a), she is Aa.

Similarly, the father also has these variants and is Aa as well.

The father can transfer either A or a, while the mother can also transfer either A or a.

As a result, their offspring can be AA, Aa, or aa. An AA genotype results in thick ears, while aa results in thin ears. The Aa genotype produces ears of intermediate thickness, akin to bunny B. This demonstrates the concept of incomplete dominance

Answer:

When ice is subjected to heat, it melts; however, the temperature remains constant at 0◦ C.

Explanation:

Solution

The heat supplied by the heater is solely utilized for the melting of the ice, thus maintaining the temperature at 0◦ C.

Once all the ice has liquefied, the temperature of the resulting water will start to rise over time.

Red ants rely on plants since they inhabit some of them and they consume sweet substances, such as sugar that comes from sugarcane, while squirrels depend on plants for nuts that they eat.
