Answer:

24 m/s²

Explanation:

The given parameters are;

The initial acceleration of the object, a = 16 m/s²

Let 'm' represent the initial mass of the object

The initial force acting on the object, F = m × a

∴ F = 16 × m = 16·m

When the mass is doubled, we have;

The new mass of the object, m₂ = 2 × m = 2·m

When the net force acting on the object triples, we have;

The new net force acting on the object, F₂ = 3 × F = 3 × 16·m = 48·m

From F = m × a, we have;

a = F/m

∴ The new acceleration of the object, a₂ = F₂/m₂

From which, by plugging in the values, we have;

a₂ = 48·m/(2·m) = 24

The new acceleration of the object, a₂ = 24 m/s².

To calculate the hours a bird can fly using the energy supplied by 4.00 grams of fat, we need to find the total energy content of the fat and then divide it by the bird's energy consumption rate.

Fat provides approximately 9 kcal of energy per gram. First, convert the energy content of the fat to watts:

4.00 grams of fat * 9 kcal/gram = 36 kcal

1 kcal = 4184 joules

36 kcal * 4184 joules/kcal = 150,624 joules

1 watt = 1 joule/second, so the bird consumes 3.70 joules per second.

Now, divide the total energy content of the fat by the bird's energy consumption rate:

150,624 joules / 3.70 joules/second = 40,704 seconds

Finally, convert the seconds to hours:

40,704 seconds / 3600 seconds/hour ≈ 11.31 hours

So, the bird can fly for approximately 11.31 hours using the energy supplied by 4.00 grams of fat.

#SPJ11

The first step is to calculate the energy that can be obtained from 4.00 grams of fat.

One gram of fat can provide approximately 9 calories of energy, which is equivalent to 37.656 joules. Therefore, 4.00 grams of fat can provide:

Energy = 4.00 grams x 9 calories/gram x 4.184 joules/calorie

Energy = 150.336 joules

Next, we can calculate the time that the bird can fly using this energy supply by using the formula:

Time = Energy / Power

where Power is the rate at which the bird consumes energy, which is 3.70 watts.

Time = 150.336 joules / 3.70 watts

Time = 40.62 seconds

Therefore, the bird can fly for approximately 40.62 seconds using the energy supply provided by 4.00 grams of fat.

False, infrared astronomy is best done with space-based telescopes due to the absorption and scattering of infrared radiation in Earth's atmosphere.

Infrared radiation is absorbed and scattered by Earth's atmosphere, which makes it difficult to detect and study from ground-based telescopes. Therefore, infrared astronomy is best done with space-based telescopes that can orbit above the atmosphere and detect infrared radiation without interference.

Additionally, space-based telescopes can provide a clearer and more comprehensive view of the infrared universe due to their ability to detect fainter sources and avoid the interference of Earthly light pollution. However, ground-based telescopes can still contribute to infrared astronomy by studying brighter infrared sources and complementing the observations made by space-based telescopes.

Answer:

I. Angle = 41.7° Northeast.

II. Vr = 7.08m/s

Explanation:

Let the two cars be denoted by A and B

Given the following data;

Mass of car A = 1232 Kg

Velocity of car A = 25.6 m/s

Mass of car B = 2028 Kg

Velocity of car B = 17.5m/s

First of all, we would solve for momentum;

Momentum = mass × velocity

Momentum, M1 = 1232 × 25.6

Momentum, M1 = 31539.2 Kgm/s

Momentum, M2 = 2028 × 17.5

Momentum, M2 = 35490 Kgm/s

Now, let's find the resultant momentum using the Pythagoras theorem;

R² = M1² + M2²

R² = 31539.2² + 35490²

R² = 994721136.6 + 1259540100

R² = 2254261237

Taking the square root of both sides, we have

Resultant momentum, R = 47479.06 Kgm/s

To find the direction;

Angle = tan¯¹(M1/M2)

Angle = tan¯¹(31539.2/35490)

Angle = tan¯¹(0.89)

Angle = 41.7° Northeast.

To find the speed;

R = (M1 + M2)Vr

47479.06 = (31539.2 + 35490)Vr

47479.06 = 67029.2Vr

Vr = 47479.06/67029.2

The resistance is measured across the height of the block, the width of the block, and finally, the length of the block is R, 16R, 36R which is Option A.

The resistance of a material is given by the formula:

R = (ρ×L)/A

where R is the resistance, ρ is the resistivity of the material, L is the length of the material, and A is the cross-sectional area of the material.

When the electrodes are connected to the top and bottom of the block, the resistance is measured across the height of the block. In this case, the length of the block is L = 1.0 cm, the cross-sectional area is A = (4.0 cm)×(6.0 cm) = 24 cm², and the resistance is R.

Using the formula above, we can solve for the resistivity of the material:

ρ = (RA)/L = (R × 24 cm²)/1.0 cm = 24R ohm-cm

Now, when the electrodes are connected across the width of the block, the length of the material is L = 4.0 cm, and the cross-sectional area is A = (1.0 cm)×(6.0 cm) = 6.0 cm². Using the formula for resistance, we get:

R_width = (ρ×L)/A = (24R ohm-cm × 4.0 cm)/6.0 cm² = 16R ohms

Finally, when the electrodes are connected across the length of the block, the length of the material is L = 6.0 cm, and the cross-sectional area is A = (1.0 cm)×(4.0 cm) = 4.0 cm². Using the formula for resistance, we get:

R_length = (ρ×L)/A = (24R ohm-cm × 6.0 cm)/4.0 cm² = 36R ohms

The amount of resistance that each resistor has, in this closed circuit, given the batteries is 3 ohms.

In a closed circuit, the total resistance (R_total) is equal to the sum of the individual resistances. We can use Ohm's law to solve for the resistance of each resistor:

Resistance (R) = Voltage (V) / Current (I)

Using Ohm's law, we can solve for the total resistance (R_total) of the circuit:

= V_total / I

= 18V / 2A

= 9 ohms

Since there are three identical resistors in the circuit, we can divide the total resistance by 3 to find the resistance of each resistor:

= 9 / 3

= 3 ohms

The velocity of the projectile at any time t is v(t) = \(4(7 - t)^3\), the acceleration of the projectile at any time t is a(t) = \(12(7 - t)^2\) and the projectile traveled 2401 meters into the bale of paper.

To find the velocity v of the projectile at any time t, we need to take the derivative of the position function s(t) with respect to time:

v(t) = s'(t)

s(t) = 2401 - (7 - t)^4, we can find v(t) by differentiating:

v(t) = d(s(t))/dt

= d(2401 - \((7 - t)^4)/\)dt

= \(-4(7 - t)^3 * (-1)\\= 4(7 - t)^3\)

To find the velocity of the projectile at t = 1, we can substitute t = 1 into the velocity function:

\(v(1) = 4(7 - 1)^3\\= 4(6)^3\)

= 4(216)

= 864 m/s

The acceleration a of the projectile at any time t is the derivative of the velocity function v(t):

a(t) = v'(t)

Differentiating v(t) =\(4(7 - t)^3\) with respect to t:

a(t) = d(v(t))/dt

\(= d(4(7 - t)^3)/dt\\= -3 * 4(7 - t)^2 * (-1)\\= 12(7 - t)^2\)

To find the acceleration of the projectile at t = 1, we can substitute t = 1 into the acceleration function:

\(a(1) = 12(7 - 1)^2\\= 12(6)^2\)

= 12(36)

\(= 432 m/s^2\)

To find how far into the bale of paper the projectile traveled, we need to evaluate the position function s(t) at t = 7:

s(7) = 2401 -\((7 - 7)^4\)

= 2401 - 0

= 2401 m

Answer:

1)substance A will require 910 J of heat to increase the temperature by 10°C.

2) Substance B

3) Substance A

Explanation:

1) The meaning of the statement: "specific heat capacity of A is 910 J/kg °C" is that 1 kg of substance A will require 910 J of heat to increase the temperature by 10°C.

2) While heating equal mass of all the three substances supplied with equal amount of heat, Substance B will gain more temperature due to the fact that substances of lesser specific heat capacity always tend to gain or loose heat within a short period of time.

3) While keeping equal mass at the three substances heated for the same temperature of 100°C and kept on a wax slab, substance A will go down more in depth due to the fact that heat is preserved for a longer period of time for substances that have higher specific heat capacity.

The change in the electrical energy of a proton would be 2.40 x 10^-16 J.

The change in electrical potential energy of a charged particle in a uniform electric field is given by the equation:

ΔPE = qEd

where q is the charge of the particle, E is the magnitude of the electric field, and d is the distance moved by the particle in the direction of the electric field.

In this case, the proton has a charge of q = 1.60 x 10^-19 C and moves a distance of d = 5 m - 2 m = 3 m in the direction of the electric field. The magnitude of the electric field is E = 5.0 x 10^2 N/C.

Substituting these values into the equation, we get:

ΔPE = (1.60 x 10^-19 C)(5.0 x 10^2 N/C)(3 m)

ΔPE = 2.40 x 10^-16 J

Therefore, the change in electrical energy of the proton as it moves from x = 5 m to x = 2 m is 2.40 x 10^-16 J.
