Aunt Mary needs to hang a picture in her bedroom. She uses a hammer to drive the nail into the wall. Find the force exerted by t

he hammer on the nail if the hammer stays in contact with the nail for 0.4s and has an impulse of 32Ns.

t = time of contact of hammer with the nail = 0.4 sec

I = impulse exerted by the hammer on the nail = 32 N s

F = force applied by the hammer on the nail

we know that , impulse is given as

I = F t                  where I = impulse , F = force , t = time

hence the impulse of hammer on nail is given as

I = F t

inserting the values

32 Ns = F (0.4 sec)

F = 32/0.4

F = 80 N

hence the force exerted by the hammer comes out to be 80 N

Movies and TV shows sometimes portray a person being thrown backwards a sizable distance as a result of being struck by a bullet
MAXImum [283]

Answer:

 R = 4.24 x 10⁻⁴ m

Explanation:

given,

mass of the person = 60.3-kg

mass of the bullet = 10 gram = 0.01 Kg

velocity of bullet = 389 m/s

angle made with the horizontal = 45°

using conservation of momentum.

M v  + m u  = ( M + m ) V

60.3 x 0 + 0.01 x 389 = (60.3 + 0.01) V

V = \dfrac{3.89}{60.31}

V = \dfrac{3.89}{60.31}

V = 0.0645 m/s

for calculation of range

R = \dfrac{V^2sin 2 \theta}{g}

R = \dfrac{0.0645^2sin 2 (45^0)}{9.8}

     R = 4.24 x 10⁻⁴ m

the distance actor fall is  R = 4.24 x 10⁻⁴ m

In a compression wave, particles in the medium move
nikdorinn [45]

in the same direction as the wave

Explanation:

In a compression wave, the particles in the medium moves in the same direction as the wave source.

A wave is generally defined as a disturbance that transmits energy.

  • There are two types of waves based on the direction through which they are propagated.
  • Transverse waves are directed perpendicularly in the direction of propagation.
  • Examples are electromagnetic waves.
  • Longitudinal waves are parallel to their source. Examples are sound waves, p-waves.
  • They are made up of series of rarefaction and compression.

A complete series circuit consists of a 12.0 V battery, a 4.70 O resistor, and a switch. The internal resistance of the battery
RoseWind [281]

With the switch open, there's no current in the circuit, and therefore
no voltage drop across any of the dissipative elements (the resistor
or the battery's internal impedance).  So the entire battery voltage
appears across the switch, and the voltmeter reads 12.0V .
