Answer:

The second option with a vertex pointing upwards.

Explanation:

A wave is a disturbance that can be transmitted through a medium without causing a permanent displacement of the particles of the medium. The two types are; longitudinal and transverse.

In transverse wave, the direction of propagation of the wave is perpendicular to the direction of vibration of the particles of the medium. Examples are; water waves, light waves, X-ray etc. While in longitudinal waves, the direction of vibration of the particles is parallel to the direction of propagation of the waves. Examples are; waves in a slinky, waves in a rope, sound waves etc.

A wave in a rope is a form of longitudinal waves. When two wave pulses move toward each other, interference is observed.

An artillery shell is launched on a flat, horizontal field at an angle of α = 40.8° with respect to the horizontal and with an i

Lina20 [59]

Answer:

1317.4 m

Explanation:

We are given that

Angle= $\alpha=40.8^{\circ}$

Initial speed = $v_0=346m/s$

We have to find the horizontal distance covered by the shell after 5.03 s.

Horizontal component of initial speed= $v_{ox}=v_0cos\theta=346cos40.8=261.9m/s$

Vertical component of initial speed= $v_{oy}=346sin40.8=226.1m/s$

Time=t=5.03 s

Horizontal distance = $Horizontal\;velocity\times time$

Using the formula

Horizontal distance= $261.9\times 5.03$

Horizontal distance=1317.4 m

Hence, the horizontal distance covered by the shell=1317.4 m

How long can you keep string cheese in the fridge?

allsm [11]

Cheese attributes its sour taste because of its lactic acid content. However, this should not be an indication to whether the cheese is spoiling already. We can tell its expiry date through the manufacturing details of the product. The product should be good to consume before the manufacturing expiry date. Every package must include expiry date in order to inform the consumer about the range of its consumability attributes. In the case where molds are present on the cheese already, cheese on some parts may not be edible already. Molds are due to the oxidation of glucose through the action of specific bacteria.

Chameleons catch insects with their tongues, which they can rapidly extend to great lengths. In a typical strike, the chameleon'

kramer

Chameleon's tongue is more fast than thought. Its long sticky tongue moves at an amazing ballistic speed which lashes out unsuspecting insects and bugs. Now let us see how fast it is.

GIven:

acceleration of the chameleon's tongue- 260 m/s
2 for 20 ms
constant speed 30 ms
50 ms total time
1/20 of a second

solution:

260 = n 
20 50
20 n = 13, 000
20 20
n= 650 m/s
