Answer:

In summer season, sun would not set at latitude 66.5 N and above. In summer season for southern hemisphere, sun would not set for latitude 66.5 S and above.

Explanation:

Season on Earth occurs due to the inclination of the axis about which it rotates. Due to this, there is different length of day and night in different hemispheres at a time.

Sun is highest in the sky in northern hemisphere in summers. So the places at 66.5 N and higher latitude experience 24 hours sun light.

Similarly, in northern hemisphere summers, places at 66.5 S and higher latitude experience 24 hours sun light.

What velocity must a 1210 kg car have in order to have the same momentum as the pickup truck in the sample problem

harina [27]

Answer:

P=mv 2250*25=56250

Explanation:

p of truck =2250*25 =56250

since p of truck = p of car

then p of car = 56250

therefore p of car = 1210 * v

or, 56520=1210v

or,v= 56520/1210=46.48

so, v of car is 46.48m/s

A particle with charge 7.76×10^(−8)C is moving in a region where there is a uniform 0.700 T magnetic field in the +x-direction.

kodGreya [7K]

Answer:

The z-component of the force is $\= F_z = 0.00141 \ N$

Explanation:

From the question we are told that

The charge on the particle is $q = 7.76 *0^{-8} \ C$

The magnitude of the magnetic field is $B = 0.700\r i \ T$

The velocity of the particle toward the x-direction is $v_x = -1.68*10^{4}\r i \ m/s$

The velocity of the particle toward the y-direction is

$v_y = -2.61*10^{4}\ \r j \ m/s$

The velocity of the particle toward the z-direction is

$v_y = -5.85*10^{4}\ \r k \ m/s$

Generally the force on this particle is mathematically represented as

$\= F = q (\= v X \= B )$

So we have

$\= F = q ( v_x \r i + v_y \r j + v_z \r k ) \ \ X \ ( \= B i)$

$\= F = q (v_y B(-\r k) + v_z B\r j)$

substituting values

$\= F = (7.7 *10^{-8})([ (-2.61*10^{4}) (0.700)](-\r z) + [(5.58*10^{4}) (0.700)]\r y)$

$\= F= 0.00303\ \r j +0.00141\ \r k$

So the z-component of the force is $\= F_z = 0.00141 \ N$

As the speed of a fluid increases, ____.

Fofino [41]

The correct answer for the question that is being presented above is this one: "a. the pressure decreases." As the speed of a fluid increases, the pressure decreases." The relationship of the speed and the pressure is inversely proportional. As the pressure increases, the speed decreases.

If you are trying to get ketchup out of the bottle, the best way to do it is to turn the bottle upside down and give the bottle

Igoryamba

Answer:

Explanation:

A body remains at rest or in motion unless or until an external force is applied. This is called Law of Inertia

Now When ketchup bottle is turned upside down and smack is applied to it, it causes the ketchup to start moving thereby disturbing its motion of rest and provide its motion.

And according to the first law state of rest is broken by applying an external force.
